Question: Look at this series: C189, H164, M144, R129,..... What should come…

Answer: W119

Explanation:

• Letters: The letters move forward by 5 positions each term (C → H → M → R corresponds to positions 3, 8, 13, 18). Adding 5 gives 23, which is W.

• Numbers: The numbers decrease by 25, 20, 15,... so the next decrease is 10. Starting from 129, subtract 10 to get 119.

Therefore the next term in the series is W119.
