Answer
Correct Answer: 48
Explanation
Introduction / Context:Find f(n) such that 6 → 35. A compact rule is f(n) = n^2 - 1 (since 6^2 - 1 = 36 - 1 = 35). Apply the same to n = 7.
Given Data / Assumptions:
- Square-based transformation.
Concept / Approach:Compute 7^2 - 1.
Step-by-Step Solution:
7^2 = 49.49 - 1 = 48.Verification / Alternative check:Check that the rule also explains the first pair perfectly.
Why Other Options Are Wrong:They do not equal 7^2 - 1.
Common Pitfalls:Trying addition/multiplication tables when a simple square relation suffices.
Final Answer:48
