Question

Find the odd one out.

1. A. JLMP
2. B. ACDG
3. C. EGHK
4. D. LNOR
5. E. QSTU (Correct answer)

Correct Answer

Option E — QSTU

Detailed Solution & Explanation

The correct answer is QSTU.

Key Points

• Pattern for others: gaps of +2, +1, +3 (e.g., JLMP: J+2=L, L+1=M, M+3=P).
• QSTU: Q+2=S, S+1=T, T+1=U — last gap is +1, not +3. QSTU breaks the pattern.

Additional Information

• Convert letters to positions (A = 1 … Z = 26) and the pattern becomes arithmetic: JLMP = 10, 12, 13, 16 → gaps +2, +1, +3.
• The same gaps hold for ACDG (1, 3, 4, 7), EGHK (5, 7, 8, 11) and LNOR (12, 14, 15, 18).
• QSTU = 17, 19, 20, 21 → +2, +1, +1. Had it followed the rule it would have been QSTW.
• In letter-cluster questions, always write the numeric positions first; three clusters sharing a gap sequence and one breaking it is the standard construction.
