SSC CPO Tier I - 11th December 2019 - Shift 1 • Reasoning • Q151

Select the option that will fill in the blank and complete the given series.

14, 17, 23, 32, 44, ______

Show answer & explanation

Correct answer: D

Explanation

The correct answer is Option 4 i.e. 59.

Understanding Application

Given series:

14, 17, 23, 32, 44, ______

The pattern followed here is:

17 - 14 = 3 = (3 × 1)

23 - 17 = 6 = (3 × 2)

32 - 23 = 9 = (3 × 3)

44 - 32 = 12 = (3 × 4)

Thus, we see that the difference between the consecutive terms is the table of 3. 

Therefore, the number that will replace the blank space will be:

44 + (3 × 5) = 44 + 15

= 59
