Pattern Analysis:
- The given number series is: 170, 120, 50, 24, 10, ?
- We need to identify the pattern in the series to find the missing number.

Step-by-Step Solution:
1. The difference between 170 and 120 is 50.
2. The difference between 120 and 50 is 70.
3. The difference between 50 and 24 is 26.
4. The difference between 24 and 10 is 14.

Identifying the Pattern:
- The differences between consecutive numbers in the series are changing.
- The differences are decreasing by 20, 16, and 12 successively.

Applying the Pattern:
- The next difference should be 10 (14 - 4 = 10).
- Therefore, the missing number should be 10 - 10 = 0.
Therefore, the number that should come in place of the question mark (?) in the series is 0. Hence, the correct answer is option 'C'.
