Which of the following numbers will replace the question mark (?) in the given series?
-1, 0, 3, 8, 15,?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 24.
Given series: -1, 0, 3, 8, 15,?
The series follows this pattern:
-1 + 1 = 0
0 + 3 = 3
3 + 5 = 8
8 + 7 = 15
15 + 9 = 24
So, the next term in the series is 24.
