Find the odd pair: In each ordered pair (A, B), the intended pattern is B = A + 11. Identify the pair that does not follow this +11 difference.

Introduction / Context:
Here, each option is an ordered pair (A, B). Most obey a constant-difference rule B = A + 11. The odd pair breaks this rule.

Given Data / Assumptions:

• Pairs: (46, 57), (38, 49), (41, 52), (64, 73).
• Compute B − A to verify the rule.

Concept / Approach:
Calculate B − A for each pair. Any result not equal to 11 flags the odd pair.

Step-by-Step Solution:

Verification / Alternative check:
Reverse differences A − B should be −11 for valid pairs; only the last gives −9, confirming the mismatch.

Why Other Options Are Wrong:
They match the +11 relation and are therefore not odd.

Common Pitfalls:
Mental subtraction errors with close numbers. Always compute carefully.

Final Answer:
64, 73 is the odd pair.
