Digit Analogy — Constant increment across the triple: (223, 324, 425) → ____

Introduction / Context:
The given triple increases by a constant value each step: 223 → 324 (+101), 324 → 425 (+101). We must select the option whose elements likewise rise by a fixed increment across the triple.

Concept / Approach:
Test options for constant differences:

• (554, 655, 756): +101, +101 ✔
• (623, 723, 823): +100, +100 ✘ (different constant than the model)
• Others: differences are inconsistent.

Final Answer:
(554, 655, 756)
