Difficulty: Easy
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:
Concept / Approach:
Track each position independently to see consistent +1 or +2 progressions.
Step-by-Step Solution:
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.
