In the following question. select the missing number of the given series.
10, 9, 17, -10, 54,?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. -71.
Given series: 10, 9, 17, -10, 54,?
The series follows this pattern:
10 - 13 = 10 - 1 = 9
9 + 23 = 9 + 8 = 17
17 - 33 = 17 - 27 = -10
-10 + 43 = -10 + 64 = 54
54 - 53 = 54 - 125 = -71
So, the next term in the series is -71.
