Solution :

Starting with the numbers in the top row, and following straight lines through the center of the diagram, subtract the middle number from the top number to give the corresponding value on the bottom row.

First raw digits  : 9, 8, 4 

Middle row digits : 2

Last row digits   : 2, 6, ?

Last line first digits : 4- 2 = 2

Last line second digit : 8 - 2 = 6

Last line last digit : 9 - 2 = 7

So answer is  7
