Answer:
A) 38
Step-by-step explanation:
This is my best take on this puzzle
The relationship between the number in the center of each grid and the other adjacent numbers is as follows:
Center number = Sum of adjacent numbers - 2
In the first grid we get
Center number = 10
Sum of adjacent numbers is 0 + 6 + 4 + 2 = 12
And 10 = 12 - 2 so the formula holds
In the second grid,
Center number = 24
Sum of adjacent numbers = 6 + 2 + 10 + 8 = 16 and
24 = 26 - 2
Again the formula holds
In the third grid, sum of adjacent numbers is
4 + 14 + 12 + 10 = 40
Center number = 40 - 2 = 38
