Answer

To find the missing term in the series: 63, 58, 51, 40, 27, ?, we will analyze the differences between the consecutive terms.

1. **Identify the terms in the series:**
- The series is: 63, 58, 51, 40, 27, ?

2. **Calculate the differences between consecutive terms:**
- 63 - 58 = 5
- 58 - 51 = 7
- 51 - 40 = 11
- 40 - 27 = 13

So, the differences are: 5, 7, 11, 13.

3. **Analyze the differences:**
- The differences are: 5, 7, 11, 13.
- These numbers are consecutive prime numbers.

4. **Find the next prime number after 13:**
- The next prime number after 13 is 17.

5. **Subtract this next prime number from the last term in the series:**
- 27 - 17 = 10.

6. **Conclusion:**
- The missing term in the series is 10.

Thus, the answer is 10.

**Final Answer: 10 (Option 3)**
