Pattern:

The given series follows a specific pattern in which the numbers are alternating between decreasing and increasing order with a gap of 1.

- Starting with 8, the next number is 9 (increasing by 1)
- The next number is 8 (decreasing by 1)
- The next number is 7 (decreasing by 1)
- The next number is 10 (increasing by 3)
- The next number is 9 (decreasing by 1)
- The next number is 6 (decreasing by 3)
- The next number is 11 (increasing by 5)
- The next number is 10 (decreasing by 1)
- The next number is missing (decreasing by 5)
- The last number is 12 (increasing by 2)

Solution:

To find the missing number, we need to continue the pattern by alternating between decreasing and increasing order with a gap of 1. Based on this pattern, the missing number can be calculated as follows:

- The last number was 10 (decreasing by 5)
- The missing number should be 5 less than the previous number, which is 5.
- Therefore, the missing number is 5.
- The next number is 12 (increasing by 2)

Hence, the correct answer is option A (5).
