Question

Three of the following four letter clusters follow a similar pattern, while one does not. Identify the letter cluster that is different from the rest.

1. A. ACEG
2. B. EGIK
3. C. MOQT (Correct answer)
4. D. IKMO

Correct Answer

Option C — MOQT

Detailed Solution & Explanation

The correct answer is MOQT.

Key Points

• Convert each cluster to letter positions and look at the gaps.
• ACEG → 1, 3, 5, 7: gaps of +2, +2, +2.
• EGIK → 5, 7, 9, 11: gaps of +2, +2, +2.
• IKMO → 9, 11, 13, 15: gaps of +2, +2, +2.
• MOQT → 13, 15, 17, 20: gaps of +2, +2, +3 — this one breaks the pattern.

Additional Information

• The odd cluster is therefore MOQT; had it followed the rule it would have been MOQS.
• For letter-series questions, writing the alphabet positions (A = 1 … Z = 26) turns a pattern-spotting task into simple arithmetic.
