Which of the following numbers will replace the question mark (?) in the given series?
16, 18, 27, 55, 120, ?

Correct option is B

Given:

Series 16, 18, 27, 55, 120, ?

Logic:

Differences between consecutive number 2, 9, 28, 65

we observe the sequence of differences, they can be related to $$n^3+1$$

​$$1^3+1=2$$

$$2^3+1=9$$

$$3^3+1=28$$

$$4^3+1=65$$

$$5^3+1=126$$

So, next differences between consecutive number is 126

Add this to the last term (120):

120+ 126 = 246

Thus, correct answer is (b)
