C, E, K, Q, W, ?

Question

C, E, K, Q, W, ?

1. A. C (Correct answer)
2. B. D
3. C. E
4. D. F

Correct Answer

Option A — A

Detailed Solution & Explanation

The correct answer is Option A.

Key Points

• Letters: C, E, K, Q, W, ?
• Convert to positions: C=3, E=5, K=11, Q=17, W=23. The gaps are +2, +6, +6, +6 — from E onward the step is +6.
• Continuing: 23 + 6 = 29. Since the alphabet has 26 letters, wrap around: 29 − 26 = 3 = C.
• So the next letter is C.

Exam Tip

• for letter series, convert to position numbers (A=1 … Z=26), find the numeric pattern, and wrap around (subtract 26) when you exceed Z.

Additional Information

• Convert to positions immediately: C=3, E=5, K=11, Q=17, W=23 — the gaps are 2, 6, 6, 6, which points to a fixed step after the first.
• Writing A-Z with position numbers before starting the reasoning section turns every letter-series question into arithmetic.
• Remember the alphabet wraps: after Z comes A again, so subtract 26 when a position exceeds it.
