Question

Find the wrong term in the letter-number series: Q1F, S2E, U6D, W12C, Y88B

• A. S2E
• B. U6D
• C. W12C
• D. Y88B

Hint:

In alphanumeric series, analyze each component (letter, number) separately for consistent patterns.

Answer 1

The Correct Option is D

Observe the letter-number-letter pattern: 1st Letters: Q(17), S(19), U(21), W(23), Y(25) — Increasing by 2 each time: ✅ Middle Numbers: 1, 2, 6, 12, 88 → Check the pattern: 1 → 2 (+1), 2 → 6 (+4), 6 → 12 (+6), 12 → 88 (+76) ❌ Clearly, +76 breaks the pattern. Last Letters: F(6), E(5), D(4), C(3), B(2) — Decreasing by 1 each time: ✅ So the anomaly is in the number 88 — the pattern is broken. Hence, Y88B is the wrong term.
