C Correct answer
Explanation

Calculate the pattern of differences: 192-187=5, 216-192=24, 277-216=61. The differences follow the pattern: 5=1×5, 24=2×12, 61=3×20+1. Alternatively, observe that the differences themselves follow a pattern where each difference is obtained by adding consecutive numbers to the previous difference. The next difference is 122, so the missing term is 277+122=399.
