Correct option is C
Let's analyze the pattern in the given number series: 975, 864, 753, 642, ?
- Look at the difference between consecutive terms:
- 975 -> 864: Subtract 111
- 864 -> 753: Subtract 111
- 753 -> 642: Subtract 111
- Subtract 111 from the last term (642):
642 - 111 = 531
Thus, the next term in the series is 531.
Correct Option: (c) 531
