Find the odd letter triple (constant step -3): Pick the option that does not decrease by 3 and then by 3 again.

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:

• G → D (−3), D → A (−3) → GDA fits.
• O → L (−3), L → I (−3) → OLI fits.
• V → S (−3), S → P (−3) → VSP fits.
• W → Y (+2), Y → Z (+1) → WYZ breaks the rule.

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:

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
