Which of the following numbers will replace the question mark (?) in the given series?
1248, 887, 598, 429, ?, 259, 234
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 308.
Given series: 1248, 887, 598, 429, ?, 259, 234
The series follows this pattern:
1248 - 192 = 1248 - 361 = 887
887 - 172 = 887 - 289 = 598
598 - 132 = 598 - 169 = 429
429 - 112 = 429 - 121 = 308
308 - 72 = 308 - 49 = 259
259 - 52 = 259 - 25 = 234
So, the missing term in the series is 308.
