Which number will replace the question mark (?) in the following number series?
24, 61, 122, 213, ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e 340.
Given series: 24, 61, 122, 213, ?
The series follows the pattern:
24 = 33 - 3 = 27 - 3 = 24
61 = 43 - 3 = 64 - 3 = 61
122 = 53 - 3 = 125 - 3 = 122
213 = 63 - 3 = 216 - 3 = 213
a = 73 - 3 = 343 - 3 = 340
a = 340
So, the next term in the series is 340.
