Find the missing term in the series given below: 2, 12, 36, ?, 150

A80 ✓ Correct

B72

C100

D86

Correct answer: (A) 80

Explanation

The missing term is 80.

Each term follows n^3 + n^2 for n = 1, 2, 3, ...

1 + 1 = 2, 8 + 4 = 12, 27 + 9 = 36.

For n = 4: 64 + 16 = 80; for n = 5: 125 + 25 = 150.

So the missing term is 80.
