There are 15 squares horizontally below, and each square has a number. If the sum of any three adjacent numbers is 16, then the number represented by w is _ _ _ _ _

According to the fact, the sum of any three adjacent numbers is equal to 16, and the number to the right of x is 7.

6 The sum of the two numbers in the space on the right is 10.

You can get that the number on the left of X is 6.

So x= 16-7-6=3,

Therefore, the numbers in the square of 15 are in the cyclic order of 6, 3 and 7.

Then w = 6.

So the answer is: 6, 3.
