What will come in place of question mark (?) in the given number series?
33 40 29 42 25 ?

Options

A. 40
B. 44
C. 52
D. 48

Answer

To solve the number series: 33, 40, 29, 42, 25, ?, we need to identify the pattern in the series.

### Step-by-step Solution:

1. **Identify the Pattern**:
- The series alternates between two sequences: one that is decreasing and one that is increasing.
- The decreasing sequence consists of: 33, 29, 25
- The increasing sequence consists of: 40, 42, ?

2. **Analyze the Decreasing Sequence**:
- From 33 to 29, we subtract 4:
\[ 33 - 4 = 29 \]
- From 29 to 25, we again subtract 4:
\[ 29 - 4 = 25 \]
- Therefore, the next term in the decreasing sequence would also be:
\[ 25 - 4 = 21 \]

3. **Analyze the Increasing Sequence**:
- From 40 to 42, we add 2:
\[ 40 + 2 = 42 \]
- To find the next term in the increasing sequence, we add 2 to 42:
\[ 42 + 2 = 44 \]

4. **Conclusion**:
- The missing term (?) in the series is 44.

Thus, the answer is **44**.
