Directions to Solve

Choose the correct alternative that will continue the same pattern and replace the question mark in the given series.


26.
45, 54, 47, ?, 49, 56, 51, 57, 53
48
50
55
None of these
Answer: Option
Explanation:

The given sequence is a combination of two series:

I. 45, 47, 49, 51, 53 and II. 54, ?, 56, 57

Clearly, II consists of consecutive natural numbers, starting from 54.

So, missing term = 55.


27.
3, 8, 13, 24, 41, ?
70
75
80
85
Answer: Option
Explanation:

The pattern followed is : nth term + (n + l)th term + (n + 1) = (n + 2)th term.

Thus, 1st term + 2nd term + 2 = 3rd term; 2nd term + 3rd term + 3 = 4th term and so on.

So, missing term = 6th term = 4th term + 5th term + 5 = 24 + 41 + 5 = 70.


28.
10, 14, 26, 42, 70, ?
100
102
106
114
Answer: Option
Explanation:

Each term in the series, except the first two terms, is 2 more than the sum of the preceding two terms.

So, missing term = (42 + 70) + 2 = 114.


29.
10, 18, 28, 40, 54, 70, ?
85
86
87
88
Answer: Option
Explanation:

The pattern is + 8, + 10, + 12, + 14, .....

So, missing term = 70 + 18 = 88.


30.
8, 28, 116, 584, ?
1752
3502
3504
3508
Answer: Option
Explanation:

The pattern is x 3 + 4, x 4 + 4, x 5 + 4,.....

So, missing term = 584 x 6 + 4 = 3508.
