14+ (14) , 28, (28-8) =20, 20+ (20) , 40, (40-8) =32, 32+ (32) , 64, (64-8) =56.
This is the right answer.

Why can't we say the Answer D.
As it was Multiplied by 2 with each number and with last 64*2 can get 128.

We can also do like this;
14 + 14=28.
28 - 8 = 20,
20 + 20 = 40,
40 - 8 = 32,
32 + 32 = 64,
64 - 8 = 56.
14 + 14=28.
28 - 8 = 20,
20 + 20 = 40,
40 - 8 = 32,
32 + 32 = 64,
64 - 8 = 56.

@Aswath.
Why 50 is not an answer? I still can't understand. Can someone explain this to me?

I have this question: A series has 17 numbers, if the second is 3, what is the fast number?

14, 20, 32.
14 + 6 = 20.
(6 + 6 = 12) 20 + 12 = 32.
(12 + 12 = 24) 32 + 24 = 56.
14 + 6 = 20.
(6 + 6 = 12) 20 + 12 = 32.
(12 + 12 = 24) 32 + 24 = 56.

Take double of the number and alternatively take difference 8. So the answer is 56.

14+6=20
20+(6*2)=32
32+(12*2)=56
Like this:
28+12=40
40+(12*2)=64
64+(24*2)=112
20+(6*2)=32
32+(12*2)=56
Like this:
28+12=40
40+(12*2)=64
64+(24*2)=112
