Step-by-step explanation:

Given:

To find:

The missing number

Solution:

• This is a numerical series that relates to the specific numbers orderly to make a series.
• We need to analyze the given series for the search of sequence.
• In the given series we need to break the series into two as (18,19,20,21) and (17,16,15,14).
• (18,19,20,21) series is arranged in ascending order smaller to bigger number order.
• (17,16,15,14) series is arranged in descending order bigger to smaller number order.

(18,19,20,21) ⇒smaller to bigger order series

Bigger to smaller number series are given by

(17, ?,15,14) ⇒(17,16,15,14)

The missing in the series is 16.

The series is 18,17,19, 16 ,20,15,21,14

Hence,

The missing number in the series is 16.

18,17,19, 16 ,20,15,21,14
