Difficulty: Medium
Correct Answer: WYZ
Explanation:
Introduction / Context:Another standard pattern uses a constant negative step between letters. When each successive letter is exactly three positions earlier in the alphabet, the triple follows a “-3, -3” rule. Any item that breaks this is the odd one out.
Given Data / Assumptions:
Concept / Approach:Translate letters to indices and check successive differences. The outlier is the only one that does not maintain the constant −3 step twice.
Step-by-Step Solution:
1) Compute two differences for each triple.2) Identify those equal to −3 and −3.3) “WYZ” yields +2 and +1, so it is the outlier.Verification / Alternative check:Reverse-reading (right-to-left) should give +3, +3 for conforming items; WYZ still fails.
Why Other Options Are Wrong:They follow the constant-step rule precisely.
Common Pitfalls:Ignore visual proximity; always compute numeric differences to avoid mistakes.
Final Answer:WYZ
