(a) 8,8
(b) 8,0
(c) 3,8
(d) None of these​

Answer 1

Answer:

Let the missing terms of the series be x 1 and x 2 .

Thus, the sequence 2, 15, 4, 12, 6, 7, x

1 ,x 2is a combination of two series :

I. 2, 4, 6, x 1

and

II. 15, 12, 7, x 2 I consists of consecutive even numbers.

So, missing term, x 1=8.

The pattern in II is - 3, - 5,......So, missing term, x 2=7−7=0.
