Alternately 14, 20, 32, 56.
14 + 6 = 20.
20 + 12 = 32.
32 + 24 = 56.
14 + 6 = 20.
20 + 12 = 32.
32 + 24 = 56.

14*2 = 28.
28-8 = 20.
20*2 = 40.
40-8 = 32.
32*2 = 64.
64-8 = 56.
28-8 = 20.
20*2 = 40.
40-8 = 32.
32*2 = 64.
64-8 = 56.

The alternative numbers are Multiplied by 2 and subtract from 8.

My Answer = 56.
14 + 6 = 20,
20 + (6*2) = 32.
32 + (12*2) = 56.
14 + 6 = 20,
20 + (6*2) = 32.
32 + (12*2) = 56.
