What should come in place of the question mark (?) in the given series based on the English alphabetical order? VUR, TSP, RQN, POL, ?
MLK
NMJ
MLI
NMK
NMJ
Observe the first letter of each cluster; they follow a -2 alphabetical sequence (V-2=T, T-2=R, R-2=P, P-2=N).
Observe the first letter of each cluster; they follow a -2 alphabetical sequence (V-2=T, T-2=R, R-2=P, P-2=N).
Analyze the 1st letter of each cluster
V (22) → T (20) → R (18) → P (16) → N (14). The pattern is -2 for each step. 16 - 2 = 14 (N).
Analyze the 2nd letter of each cluster
U (21) → S (19) → Q (17) → O (15) → M (13). The pattern is -2 for each step. 15 - 2 = 13 (M).
Analyze the 3rd letter of each cluster
R (18) → P (16) → N (14) → L (12) → J (10). The pattern is -2 for each step. 12 - 2 = 10 (J).
A: MLK is incorrect as the sequence requires -2 for all letters resulting in NMJ, C: MLI is incorrect as the third letter must be J, D: NMK is incorrect as the third letter must be J.
B is correct because each letter in the cluster shifts back by 2 positions in the English alphabet (V-2=T, T-2=R, R-2=P, P-2=N; U-2=S, S-2=Q, Q-2=O, O-2=M; R-2=P, P-2=N, N-2=L, L-2=J).
For alphabetical series, always write the numeric positions (A=1, B=2... Z=26) above the letters to instantly spot arithmetic sequences.
