Show answer & explanation

Correct answer: A

Explanation

The correct answer is Option 1 i.e. 42.

Understanding

Given series: 63, 63, 56, 56, 49, 49, 42,?

The series follows this pattern:

63 - 0 = 63

63 - 7 = 56

56 - 0 = 56

56 - 7 = 49

49 - 0 = 49

49 - 7 = 42

42 - 0 = 42

So, the next term in the series is 42.
