Q: For example, try 11, 12, 13, 14; 14 x 4 = 56, and 56 - 6 = 50. Or, you can multiply the sum of the middle two numbers by two. In the above case, 12 + 13 = 25, and 25 x 2 = 50. Say you have a consecutive series from 11 through 16. You’d multiply 16 x 6 = 96, then subtract 15 to get 81. Alternatively, you can multiply the sum of the middle two numbers by 3. In the above case, 13 + 14 = 27, and 27 x 3 = 81. If your series runs from 11 through 17, 14 is the middle number. Thus, 14 x 7 = 98. For any odd number (3, 5, 7, etc.) of consecutive numbers, you can always just multiply the middle number by the total number in the series. If your numbers run from 11 through 18, multiply 18 x 8 = 144, then subtract 144 - 28 = 116. You can also multiply the sum of the middle two numbers by 4. In the above example, 14 + 15 = 29, and 29 x 4 = 116.
A: Add four consecutive numbers by multiplying the highest by 4 and subtracting 6. Add six consecutive numbers by multiplying the highest by 6 and subtracting 15. Add seven consecutive numbers by multiplying the middle number by 7. Add eight consecutive numbers by multiplying the highest by 8 and subtracting 28.

Article: Certain websites allow skilled or knowledgable people to record lessons that others can pay to view. The teachers then can participate in forums to help their students through difficult parts of their content. Doing this not only allows you to share your skills with other people, but also earns a steady stream of income if many people participate in your class. People love buying interesting crafts and hand-made objects. Online stores like Etsy allow creative and crafty people to make money by selling their products. Be sure to enter the marketplace with something that differentiates your product from other offerings already available on the site. There are a number of sites that connect skilled individuals with people in need of those skills. Whether you are a graphic designer, lawyer, or translator, you can find someone willing to pay you a reasonable amount for your work. Try searching for "freelance work online" and check out the first few results. While it may seem like a daunting task to write an entire book, Ebooks do not need to be long to be informative and valuable. You just have to figure out what you know how to do that others would want to know and organize your information in book format. Of course the actual writing process will take time, but with online publishing services, publishing and selling your eBook will be a breeze.  Your eBook can be easily published using a variety of online publishing services, such as those hosted by Google, Amazon, and Barnes and Noble. At each site you can submit your book and, once it is approved, will be listed for sale. Because your book is digital, the copies cost you nothing to sell. Excluding time to write and convert to eBook format, you may earn a profit. However, average revenues from an ebook are less than $300. There are lots of competitors, many of whom spend hours promoting their books. So you may earn money from this venture, but don't expect to bring in a huge profit. YouTube allows content creators to earn money from advertising based on how many views they receive. The payout isn't much, about $1–$3 per 1000 views, but that can add up quickly with as you post more videos and gain more viewers. An added benefit here is that you can create videos about whatever you want, as long as you think others will want to watch it.  Be aware that videos, like eBooks, are unlikely to bring in much money. You face an enormous amount of competition, and it's pretty unlikely your videos will be viewed by anyone other than family and friends.

Teach online classes. Sell your hand-made goods online. Sell your skills. Write an eBook. Create YouTube Videos.

Problem: Article: Sleep is very important for giving your muscles a chance to grow. Getting at least seven hours of sleep a night is the minimum, 8-9 is ideal. You might enjoy other cardio activities (sports, running, etc.) but those put additional strain on your body (muscles, joints) and use up energy that could be used instead to build muscle. Normally, cardio activities should definitely be included for all-around health, but if you're temporarily focused on building muscle quickly, focusing on weight-training exclusively for a few months will help you reach that goal.
Summary: Get more than enough sleep. Focus exclusively on weight-training.

INPUT ARTICLE: Article: Your first morning urine will contain the highest concentration of a substance since it has had a chance to build up overnight. Do not go to the testing facility without urinating first! Urinate before you leave the house. For example, if your test is at 9:00 am, get up at 7:00 am and urinate right away. Drinking lots of fluid before a urine test is also known as “washing” and it’s one of the most common techniques for passing a urine test when you don’t have much time to prepare yourself. Start drinking water the morning of your test or at least 2 hours before your test to increase your fluid output and dilute the substances in your urine. For example, if your drug test is scheduled for 11:00 am, wake up by start drinking water by 9:00 am. When you start drinking extra water, your urine will become pale, and this can be a giveaway to the drug testers that you have been drinking an excessive amount of water to dilute your urine. To disguise this fact, take a B-complex vitamin when you start drinking water. This will make your urine look darker and reduce the chances that you’ll be suspected of “washing.”  For example, if you start drinking water at 9:00 am, take a B-complex vitamin at the same time. You can purchase a bottle of B-complex vitamins at a grocery or drug store. Taking an over-the-counter diuretic a couple of hours before your test might help to dilute your urine by increasing your fluid output. Diuretic pills are available in most drug and grocery stores.  Don’t exceed the recommended dosage! Follow the manufacturer’s instructions for use. Coffee, tea, and cranberry juice also have mild diuretic effects if you don’t want to go out and buy diuretic pills. Although it’s not foolproof, one study showed that adding a few drops of Visine to urine helped to lower its THC concentration. If you are able to produce your sample in a private room, then you could add a few drops of Visine to the urine after you produce your sample. Make sure that you are not being monitored if you try this! Getting caught tampering with your sample may result in an automatic fail, and depending on where you live, you could find yourself in legal trouble as well.

SUMMARY: Urinate at home on the morning of the test. Drink at least 24  fl oz (710 mL) of water in the 2 hours before your test. Take a B-complex vitamin to color your urine. Try taking an over-the-counter diuretic to boost your fluid output. Add Visine to your urine if you’re being tested for marijuana.

Q: This style of roll is one of the easier styles and doesn’t strictly require styling cream. However, you may find it useful if you have especially fine hair or hair that is prone to flyaways. After using the mousse, brush your hair thoroughly. With one side of your hair clipped up, twist the other side of your hair into individual twists, and then combine to make another large twist. You should now have two twists on either side. Since this is a modern and elegant look, you will want to make sure that your hair is free of frizziness or bumps. Take a comb and smooth down any messy spots. Clip any fine hair in place with bobby pins. Then use hairspray on the rolled section of hair.
A:
Use styling mousse for fine hair. Repeat the twisting on the other side. Comb down hair.
