Analogy (number triple) — (12, 5, 7). Select the option where the first number equals the sum of the second and third.

Introduction / Context:
In number analogies, a hidden rule ties the positions. For (12, 5, 7), observe that 5 + 7 = 12. We must choose a triple that preserves “first = second + third.”

Given Data / Assumptions:

• Structure: (A, B, C) with A = B + C.
• All numbers are integers.

Concept / Approach:
Test each candidate quickly for B + C = A.

Step-by-Step Solution:

Verification / Alternative check:
Only option (7, 4, 3) satisfies the required sum relation exactly.

Why Other Options Are Wrong:
They fail the equality check “first = second + third.”

Common Pitfalls:
Assuming a product or difference rule; the direct sum rule is faster and consistent with the prompt.

Final Answer:
(7, 4, 3)
