this is weird, because i came up with two variations, both resulting in the same outcome, of 14. I guess it is all relative though, since you would be subracting the numbers and multiplying by two. Add diagonally and subtract the two numbers, then multiply….

The missing number is 14! It took me 2.5 minutes to find the pattern.

I think one answer can be this: 14

sum the diagonals then substract the value then X 2

Explanation:

1) 15+7= 22; 6+12= 18 –>22-18= 4 X 2= 8
2) 6+9= 15; 2+4= 6–> 15-6 = 9 X 2= 18
so:
3) 11+8= 19; 5+7= 12—> 19-12= 7 X 2= 14

The missing number is 14.

8 = 2*((15+7) – (6+12))
18 = 2*((6+9) – (2+4))
14 = 2*((11+8) – (5+7))

[(15-12) + (7-6)]x2 = 8
[(6-4) + (9-2)]x2=18
[(11-7) + (8-5)]x2 =14
So the answer might be 14. But somebody else might have found different patterns…
