Pattern Analysis:
The given number series is increasing with each subsequent number. Let's analyze the difference between consecutive numbers to identify the pattern.

Calculation of Differences:
- Difference between 57 and 42 = 15
- Difference between 87 and 57 = 30
- Difference between 132 and 87 = 45
- Difference between 192 and 132 = 60

Pattern Identification:
The differences between consecutive numbers are increasing by multiples of 15. Hence, the next difference should be 75.

Prediction for the Next Number:
To find the next number in the series:
- 192 + 75 = 267
Therefore, the next number in the series should be 267.

Conclusion:
The missing number in the series is 267, which is represented by option (a).
