Find the missing number in the series

2, 6, 12, 20, ?, 42, 56

Answer

Correct Answer : b ) 30

Explanation :

Let's look at the series and try to visualize what pattern it is making:

2 = 1² + 1

6 = 2² + 2

12 = 3² + 3

20 = 4² + 4

? = 30 = 5² + 5

42 = 6² + 6

56 = 7² + 7

Therefore, the missing number is 30.
