13. (12 points) The teacher wrote down consecutive odd numbers starting from 1 on the blackboard, forming a long string of numbers. After erasing two of these numbers, the remaining odd numbers were divided into 3 segments. It is known that the second segment has 1 more number than the first segment, the third segment has 1 more number than the second segment, and the sum of the odd numbers in the third segment is 4147. What is the sum of the two erased odd numbers?
A. 188
B. 178
C. 168
D. 158
【Solution】Solution: Let the first segment have $n$ items, then the second segment has $n+1$ items, so the first odd number erased is $2n+1$, and the second odd number erased is $4n+5$. The sum of the two erased odd numbers is: $2n+1+4n+5=6n+6$. $6n+6$ is a multiple of 6. Among the four options, only 168 is a multiple of 6, which meets the requirement. Therefore, the answer is: $C$.
