A 8, 8

B 8, 0

C 3, 8

D None of these

ANS:B - 8, 0

Explanation: Let the missing terms of the series be x1 and x2. Thus, the sequence 2, 15, 4, 12, 6, 7, x1 x2 is a combination of two series : I. 2, 4, 6, x1 and II. 15, 12, 7, x2I consists of consecutive even numbers. So, missing term, x1 = 8. The pattern in II is - 3, - 5,......So, missing term, x2 = 7 - 7 = 0.
