2, 15, 4, 12, 6, 7, ?, ?
8, 8
8, 0
3, 8
None of these
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.
