What will come in place of the question mark in the following numerical series?

6, 9, 14, 21, 30, ?

✅ Correct Option: 2

The series is: 6, 9, 14, 21, 30, ?

Finding the differences between consecutive terms:

$9 - 6 = 3$

$14 - 9 = 5$

$21 - 14 = 7$

$30 - 21 = 9$

The differences form a sequence: 3, 5, 7, 9

These differences increase by 2 each time, forming an arithmetic progression.

The next difference in the pattern:

$9 + 2 = 11$

The next term in the series:

$30 + 11 = 41$

Therefore, the answer is Option 2: 41
