D. 63.85

Explanation

To find the missing number in the series: 980, 392, 156.8, ?, 25.088, 10.0352, we will analyze the pattern in the series.

### Step-by-Step Solution:

1. **Identify the Pattern:**
- The numbers in the series are decreasing, and they are also transitioning into decimal values. This suggests that a division operation might be involved.

2. **Divide the First Two Numbers:**
- Let's divide the first number by the second number:
\[ \frac{980}{392} = 2.5 \]
- This indicates that each number in the series is obtained by dividing the previous number by 2.5.

3. **Verify the Pattern with the Next Number:**
- Now, let's check if this pattern holds true for the next number:
\[ \frac{392}{2.5} = 156.8 \]
- This confirms that the pattern is consistent.

4. **Find the Missing Number:**
- Continuing with the pattern, we will find the missing number by dividing 156.8 by 2.5:
\[ \frac{156.8}{2.5} = 62.72 \]
- Thus, the missing number in the series is 62.72.

5. **Verify the Next Number:**
- To ensure the series continues correctly, we can check the next number:
\[ \frac{62.72}{2.5} = 25.088 \]
- This confirms our missing number is correct.

6. **Final Verification:**
- Finally, we can check the last part of the series:
\[ \frac{25.088}{2.5} = 10.0352 \]
- This further validates that our pattern holds throughout the series.

### Conclusion:
The missing number in the series is **62.72**.
