What should come in place of the question mark (?) in the given series?
327, 304, 271, ?, 175, 112
Logic: The difference between consecutive numbers is increasing by 10 in each step.
| Step | Calculation | Difference |
|---|---|---|
| 1 | 327 - 304 | 23 |
| 2 | 304 - 271 | 33 (23 + 10) |
| 3 | 271 - 43 | 43 (33 + 10) |
| 4 | 228 - 175 | 53 (43 + 10) |
| 5 | 175 - 112 | 63 (53 + 10) |
The missing number is 271 - 43 = 228.
Correct Answer: 228
