Text Solution

Verified by Experts

The correct Answer is:

B

Let the missing terms of the series be `a_(1)`, and `a_(2)`. The given sequence 2, 15, 4, 12,6,7,`a_(1)a_(2)` is a combination of two series:
I. 2,4,6, `a_(1)` and
II. 15,12,7 `a_(2)`
The pattern in I consists of consecutive even nubers i.e.

Therefore, missing term, `a_(1) = 8`.
The pattern in II is - 3, - 5, - 7 .... i.e.

Therefore, missing term, `a_(2) = 7 -7 = 0`.
