Answer
Correct Answer: Y
Explanation
Introduction / Context:In position-wise letter series, each column (1st, 2nd, 3rd letters) typically follows its own alphabetic progression.
Given Data / Assumptions:
- Triples: F O X, G P ?, H Q Z.
- Alphabet index: A=1 … Z=26.
Concept / Approach:Track each position independently to see consistent +1 or +2 progressions.
Step-by-Step Solution:
1st letters: F(6) → G(7) → H(8): +1 each step.2nd letters: O(15) → P(16) → Q(17): +1 each step.3rd letters: X(24) → ? → Z(26): +1 each step implies Y(25).Verification / Alternative check:Rewriting as three parallel sequences (FGH), (OPQ), (XYZ) makes the pattern obvious.
Why Other Options Are Wrong:Z would overshoot; T and W do not fit the +1 trajectory.
Common Pitfalls:Looking for constant shifts across whole triples rather than column-wise shifts.
Final Answer:Y.
