Answer

To find the missing number in the series 48, 52, 49, 51, ?, we can analyze the pattern of the numbers.

1. **Identify the series**: The given series is 48, 52, 49, 51, ?.

2. **Look for a pattern**:
- The first number is 48.
- The second number is 52, which is 48 + 4.
- The third number is 49, which is 52 - 3.
- The fourth number is 51, which is 49 + 2.

3. **Establish the pattern**:
- The pattern alternates between adding and subtracting:
- From 48 to 52: +4
- From 52 to 49: -3
- From 49 to 51: +2

4. **Continue the pattern**:
- Following the established pattern, the next operation should be a subtraction.
- The last operation was +2 (from 49 to 51), so we will subtract 1 from 51.

5. **Calculate the next number**:
- 51 - 1 = 50.

6. **Conclusion**:
- The missing number in the series is 50.

Thus, the answer is 50.
