A Correct answer
Explanation

Differences: 136-117=19; 154-136=18; 171-154=17; 187-171=16. Next difference is 15. 187+15 = 202.

AI explanation

The differences between the consecutive terms decrease by 1 each time. The sequence increases by 19, then 18, then 17, then 16. Subtracting 15 from 187 gives the missing number 202.
