What will be the values of P and Q in the following number series? 2, 0, 6, 6, 12, 24, P, Q

A48, 96

B20, 60 ✓ Correct

C12, 120

D48, 50

Correct answer: (B) 20, 60

Explanation

P = 20 and Q = 60.

Terms at positions 1, 3, 5, 7 follow n(n + 1): 2, 6, 12, so P = 4 x 5 = 20.

Terms at positions 2, 4, 6, 8 follow (n - 1)n(n + 1): 0, 6, 24.

For the next such term, 3 x 4 x 5 = 60.

So P = 20 and Q = 60.
