jason| Profile December 20th, 2007 - 9:14 amthis 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….

notovitz| Profile December 20th, 2007 - 10:39 amThe missing number is 14! It took me 2.5 minutes to find the pattern.

suineg| PUZZLE MASTER | Profile December 20th, 2007 - 11:35 amI 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

Ryan| Profile December 21st, 2007 - 12:37 pmThe missing number is 14.

8 = 2*((15+7) – (6+12))

18 = 2*((6+9) – (2+4))

14 = 2*((11+8) – (5+7))

Jantar| Profile December 22nd, 2007 - 6:15 amwhat about some criss-cross subtraction, addition and then doubling?

[(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…
