The answer is 6

The sum of the opposite side is equal to 21. 15+x =21 --> x = 6.

Opposite pie pieces sum to 21. We have 15 opposite ?, so the answer is:



Comment 86/500

so the upper left quarter adds up to 14, then the lower left adds up to 23 which is 9 more and the lower right adds up to 28 another increase of 5. So let's deduct a pattern here.. step 1 = 9, step 2 = 5 step 3..


Yeah, @definethedollar got it right it's 6 and has nothing to do with the quarters! Hope there's more challenge for the next one ;-)

The Answer is 6, opposites add up to 21

By a simple observation we can see that opposite pies, when added give a total of 21.
Following that logic we formulate this equation for the unknown pie, where we need to solve for x:
15 + x = 21
we subtract 15 from both sides and get x = 21-15 = 6
Therefore, the answer is 6

Each time we add opposite numbers we get the same number which is 21, so if we add 15 + ? we must get 21, so the should replace the question mark by 6
