Final answer:
The missing term in the sequence is 179. The difference between consecutive terms is constant, so the missing term can be found by adding the difference to the previous term.
Step-by-step explanation:
The missing term in the sequence is 179. The sequence starts with 34 and is followed by 177, 345, and so on. To find the pattern in the sequence, we can subtract consecutive terms. The differences are: 143, 168, and 168. We can see that the differences are constant, so the missing term should be the previous term (345) plus the difference (168), which is 179.
