Select the letter-cluster from among the given options that can replace the question mark (?) in the following series.
VQL, RMH, NID, JEZ, ?
- AFAV
- BHFD
- CROI
- DEZS
Solution & Step-by-step Explanation
Let's trace the pattern step-by-step for each letter slot across the series:
First Letter: V → R → N → J → ?
V (22) - 4 = R (18)
R (18) - 4 = N (14)
N (14) - 4 = J (10)
J (10) - 4 = F (6)
Second Letter: Q → M → I → E → ?
Q (17) - 4 = M (13)
M (13) - 4 = I (9)
I (9) - 4 = E (5)
E (5) - 4 = A (1)
Third Letter: L → H → D → Z → ?
L (12) - 4 = H (8)
H (8) - 4 = D (4)
D (4) - 4 = Z (26)
Z (26) - 4 = V (22)
Combining these letters results in the cluster FAV.
