Choose the correct alternative that will continue the same pattern and replace the question mark in the given series.
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.
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.
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.
The pattern is + 8, + 10, + 12, + 14, .....
So, missing term = 70 + 18 = 88.
The pattern is x 3 + 4, x 4 + 4, x 5 + 4,.....
So, missing term = 584 x 6 + 4 = 3508.
