Question

Select the letter-cluster from among the given options that can replace the question mark (?) in the following series: A E I, E I M, I M Q, M Q U, ?

1. A. QUY (Correct answer)
2. B. QKS
3. C. LMX
4. D. KJS

Correct Answer

Option A — QUY

Detailed Solution & Explanation

The correct answer is QUY.

Key Points

• Each cluster overlaps the previous one: take its last two letters, then add the next letter +4 places on.
• A E I → E I M → I M Q → M Q U, so the next keeps U and Q's successor pattern: Q, U, then U + 4 = Y.
• That gives Q U Y.
• Track the overlap-and-add rule rather than reading each cluster separately — the wrong options break the +4 step.

Additional Information

• Letter-series questions almost always rest on a fixed alphabetical step, an overlap between adjacent groups, or a positional (column-wise) rule.
• Write the alphabet with positions A=1 … Z=26 before starting; converting to numbers turns letter jumps into ordinary arithmetic and makes wraps past Z obvious.
• A cluster series that repeats letters from the previous group is the overlap type — check that before assuming a plain shift.
