Series and Odd Man out Practice Test 1

Question : 3 of 40

Marks: +1, -0

112, 114, 120, 124, 132, 142, 154

Solution:

Concept:

The series should follow a fixed pattern of differences between successive terms.

Explanation:

Check the differences between the given terms.

114 - 112 = 2

120 - 114 = 6

124 - 120 = 4

132 - 124 = 8

142 - 132 = 10

154 - 142 = 12

The differences should be

2, 4, 6, 8, 10, 12

Here,

6

comes in place of

4

, so

120

is the wrong term.

Replacing

120

with

118

gives

112, 114, 118, 124, 132, 142, 154

Now the differences are

2, 4, 6, 8, 10, 12

Answer:

120

is the wrong term, which is option E.
