14 * 2 = 28,
20 * 2 = 40,
32 * 2 = 64,
20 - 14 =6 and 32 - 20 = 12,
6 * 2 = 12,
12 * 2 = 24,
So that 32 + 24 = 56(answer).
20 * 2 = 40,
32 * 2 = 64,
20 - 14 =6 and 32 - 20 = 12,
6 * 2 = 12,
12 * 2 = 24,
So that 32 + 24 = 56(answer).

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

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

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.

14*2=28
20*2=40
32*2=64
64*2=128 I think 128 also the correct answer.
20*2=40
32*2=64
64*2=128 I think 128 also the correct answer.

It ca be like that,
14*2 = 28
20*2= 40
32*2= 64.
Then the difference between 14and 20 6,
Then between 32 and 20 12,
Then now 18 should be added to 32 then it will be 50.
14*2 = 28
20*2= 40
32*2= 64.
Then the difference between 14and 20 6,
Then between 32 and 20 12,
Then now 18 should be added to 32 then it will be 50.
