    2+7+6 is 15, 2+9+4 is also 15,4+3+8 is also 15 and 6+1+8 is also 15.This pattern goes vertically and horizontally with 3 numbers.
    Next,7+3 is 10 and 9+1 is also 10.This pattern also goes vertically and horizontally but only with 2 numbers.
    So, the answer is in the last and final equation.To get the ?, we need to take
    15-10 and the answer is 5.
    Reason:We take the 2 total numbers and
    minus and get the answer for ?.
