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.

28-20=8,
40-32=8,
64-8=56,
So, 56 is the right answer.
40-32=8,
64-8=56,
So, 56 is the right answer.
