anonymous · Answer

That one is a bit easier. The difference between the first two integers is x or 6-3 = 3. The difference between the next two integers is y or 12-6 = 6. See the pattern? The difference between y and x is 3. So the next "difference" would be 3+3+3 = 9.

Adding 9 to 12 gives us ... 21!
