Answer : 68

Explanation :

As you move down, multiply each number by 2 and subtract 4.

           6 x 2 = 12, 12 - 4 = 8 

           8 x 2 = 16, 16 - 4 = 12 

          12 x 2 = 24, 24 - 4 = 20 

          20 x 2 = 40, 40 - 4 = 36

          36 x 2 = 72, 72 - 4 = 68

Solution :

Taking any series of 3 numbers in a straight line in the diagram, their total is always 19.

                   6 + 9 + 4 = 19

                   2 + 11 +6 = 19

                   2 + 16 + ? = 19 = 2 + 16 + 1 = 19 

                   4 + 14 + ? = 19 = 4 + 14 + 1 = 19

                   So answer is  1.
