Which of the following numbers will replace the question mark (?) in the given series?

11, 31, 55, 84, 119, (?)

Given: 11, 31, 55, 84, 119, (?)

Logic: Here double difference pattern follows, The difference between the difference of the given terms is a series of consecutive natural numbers (4, 5, 6, 7).

11 + 20 = 31

31 + (20 + 4) = 31 + 24 = 55

55 + (24 + 5) = 55 + 29 = 84

84 + (29 + 6) = 84 + 35 = 119

Similarly, 119 + (35 + 7) = 119 + 42 = 161​

So, the correct answer is (b).
