Which of the following numbers will replace the question mark (?) in the given series?
90, 211, 67, 236, ?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 40.
Given series: 90, 211, 67, 236,?
90 + 112 = 90 + 121 = 211
211 - 122 = 211 - 144 = 67
67 + 132 = 67 + 169 = 236
236 - 142 = 236 - 196 = 40
So, the next term in the series is 40.
