Question

In the following question, select the odd letter/letters from the given alternatives.

1. A. KLIO (Correct answer)
2. B. RSPT
3. C. VWTX
4. D. HIFJ

Correct Answer

Option A — KLIO

Detailed Solution & Explanation

The correct answer is KLIO.

Key Points

• Check the internal gaps of each group. In RSPT: R→S is +1, S→P is −3, P→T is +4.
• VWTX: V→W is +1, W→T is −3, T→X is +4. Same pattern.
• HIFJ: H→I is +1, I→F is −3, F→J is +4. Same pattern.
• KLIO: K→L is +1, L→I is −3, but I→O is +6, not +4.
• KLIO breaks the pattern and is the odd one out.

Additional Information

• The gap pattern here is +1, −3, +4, mixing forward and backward steps — a reminder that these sequences need not move in one direction only.
• Because negative gaps are involved, work with signed differences and keep the sign, rather than treating each gap as a distance.
• A practical tip: once a pattern is found in the first two options, test it against the remaining ones rather than deriving it afresh each time — the odd group is the one that breaks it.
