Which of the following letter-number clusters will replace the question mark (?) in the given series to make it logically complete? ZSL 18, VOH 29, RKD 40, NGZ 51, JCV 62, ?
FYR 73
Track the first letter of each cluster: Z, V, R, N, J — each one moves back by 4 (Z→V→R→N→J), so the next first letter is J − 4 = F.
Track the second letter: S, O, K, G, C — each moves back by 4 (S→O→K→G→C), so the next second letter is C − 4 = Y.
Track the third letter: L, H, D, Z, V — each moves back by 4 (L→H→D→Z→V, wrapping past A), so the next third letter is V − 4 = R.
Track the numbers: 18, 29, 40, 51, 62 — each increases by 11, so the next number is 62 + 11 = 73.
Hence, the missing cluster is FYR 73.
