Question

Which of the following letter-number clusters will replace the question mark (?) in the given series to make it logically complete? MCK 10, PFN 13, SIQ 16, VLT 19, ?

1. A. YOW 22 (Correct answer)
2. B. XPW 24
3. C. XOV 22
4. D. YPV 22

Correct Answer

Option A — YOW 22

Detailed Solution & Explanation

The correct answer is YOW 22.

Key Points

• Split the cluster into four independent sequences and advance each:
  • 1st letters: M → P → S → V → Y (each +3)
  • 2nd letters: C → F → I → L → O (each +3)
  • 3rd letters: K → N → Q → T → W (each +3)
  • Numbers: 10 → 13 → 16 → 19 → 22 (each +3)
• Every component advances by 3, giving YOW 22.

Additional Information

• The uniform +3 across all four components makes this one of the more straightforward series types once the components are separated — the difficulty is entirely in not reading the cluster as a single unit.
• Verify each column against all given terms rather than just the last one. A shift confirmed across four terms is a rule; confirmed across two it may be coincidence.
• The distractors break individual columns: XOV 22 shifts the 1st and 3rd letters by 2, YPV 22 breaks the 2nd and 3rd, and XPW 24 breaks three components at once.
• Alphabet positions keep the additions reliable: V=22 → Y=25, L=12 → O=15, T=20 → W=23.
