Question

Complete the series: A1B, D4E, H9I, M16N, ?

• A. S25T
• B. R25S
• C. R24S
• D. S25R

Hint:

For series questions, analyze patterns separately for letters and numbers. Check differences, squares, or positions in the alphabet.

Answer 1

The Correct Option is A

Step 1: Analyzing the pattern — Letters: A, D, H, M → +3, +4, +5 (increasing gap). Numbers: 1, 4, 9, 16 → squares of 1, 2, 3, 4. Last letters: B, E, I, N → +3, +4, +5 (matches first letters).
Step 2: Next term — First letter: M +6 → S; number: 16 → 25 (5² → 6² pattern); last letter: N +6 → T.
Step 3: Conclusion — Option (a) S25T is correct.
