Find the missing term: 2, 15, 4, 12, 6, 7, ?, ?
Answer & Solution
Correct Answer:
Option
B
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, x2
I consists of consecutive even numbers. So, missing term, x1= 8
The pattern in II is - 3, - 5, ........So, missing term x2 = 7 - 7 = 0
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, x2
I consists of consecutive even numbers. So, missing term, x1= 8
The pattern in II is - 3, - 5, ........So, missing term x2 = 7 - 7 = 0
