Step 1: Analyze the transformation from "FACED" to "GZDDE"
Compare each letter:
1. F → G: The letter increases by +1.
2) A → Z: The letter decreases by -1.
3) C → D: The letter increases by +1.
4) E → D: The letter decreases by -1.
5) D → E: The letter increases by +1.
Observed pattern:
The transformation alternates between +1 and -1 for each letter.
Step 2: Analyze the transformation from "VACAY" to "WZDZZ"
Compare each letter:
1. V → W: The letter increases by +1.
2) A → Z: The letter decreases by -1.
3) C → D: The letter increases by +1.
4) A → Z: The letter decreases by -1.
5) Y → Z: The letter increases by +1.
Observed pattern:
This transformation also alternates between +1 and -1 for each letter.
Step 3: Apply the pattern to "LABOR"
Transform each letter:
1. L → M: Increase by +1.
2) A → Z: Decrease by -1.
3) B → C: Increase by +1.
4) O → N: Decrease by -1.
5) R → S: Increase by +1.
