What should come in place of the question mark (?) in the given series?
55, 64, 81, 106, 139, ?
Given:
55 64 81 106 139 ?
Logic:
The DOUBLE difference between consecutive terms is 8.
Explanation (applied left to right):
64 - 55 = 9
81 - 64 = 17
106 - 81 = 25
139 - 106 = 33
The differences are increasing by 8 each time (9, 17, 25, 33). So, the next difference will be 33 + 8 = 41.
Now, add this difference to the last number:
139 + 41 = 180.
Final Answer:
180
Final Correct Option:
(B)
