Which of the following options should come in place of the question mark (?) in the given series based on the English alphabetical order? ORN, QTP, SVR, UXT,?
WVZ
WZV
VZW
VWZ
WZV
Observe the progression of each letter position separately: the first letter jumps by +2, the second by +2, and the third by +2 in each step.
Observe the progression of each letter position separately: the first letter jumps by +2, the second by +2, and the third by +2 in each step.
Analyze the pattern of the first letter
O (+2) = Q, Q (+2) = S, S (+2) = U, U (+2) = W. The first letter of the next term must be W.
Analyze the pattern of the second letter
R (+2) = T, T (+2) = V, V (+2) = X, X (+2) = Z. The second letter of the next term must be Z.
Analyze the pattern of the third letter
N (+2) = P, P (+2) = R, R (+2) = T, T (+2) = V. The third letter of the next term must be V.
Combine the letters
Combining W, Z, and V results in the term WZV.
A: WVZ is incorrect because the third letter sequence (N-P-R-T) leads to V, not Z. C: VZW is incorrect as the first letter sequence (O-Q-S-U) leads to W, not V. D: VWZ is incorrect as it fails all three letter positional pattern shifts.
B is correct because the series follows a consistent +2 shift for each of the three positions in the triplet (O+2=Q, R+2=T, N+2=P; Q+2=S, T+2=V, P+2=R; S+2=U, V+2=X, R+2=T; U+2=W, X+2=Z, T+2=V).
When solving letter series, always write the positional numbers (A=1, B=2...) above each letter to quickly identify the numerical jump pattern.
