The sum of the squares of two consecutive multiples of 7 is 637. Find the multiples.

Explanation

To solve the problem, we need to find two consecutive multiples of 7 whose squares sum up to 637. Let's break down the solution step by step.

### Step 1: Define the Multiples
Let the first multiple of 7 be represented as \( 7x \). Therefore, the next consecutive multiple of 7 will be \( 7(x + 1) \).

### Step 2: Set Up the Equation
We need to find the sum of the squares of these two multiples:
\[
