Question

Select the letter-cluster from among the given options that can replace the question mark (?) in the following series.

BGL, GLQ, LQV, QVA, ?

1. A. ZAS
2. B. OKS
3. C. VAF (Correct answer)
4. D. AVG

Correct Answer

Option C — VAF

Detailed Solution & Explanation

The correct answer is VAF.

Key Points

• Write the alphabet positions: BGL = 2, 7, 12 — each letter is +5 from the last.
• The same +5 holds inside every cluster, and the clusters themselves start at B(2), G(7), L(12), Q(17), V(22) — also +5.
• So the next cluster starts at V; V + 5 wraps past Z to A, and A + 5 = F, giving VAF.

Additional Information

• Wrap-around is the whole difficulty here: after Z the count restarts at A, so V(22) + 5 = 27 → 27 − 26 = 1 = A.
• Convert clusters to numbers before looking for a rule — letter series become arithmetic and the pattern is obvious.
• Check both dimensions in cluster series: the step *within* a cluster and the step *between* clusters. Here they happen to be the same.
