Explanation:

Pattern:

- Similarly, we need to find a number that is a perfect square of some number to match the pattern.

Calculations:
- The square root of 337 is approximately 18.36.
- Since we need an integer, we look for the closest perfect square to 337, which is 324 (18 x 18 = 324).
- Therefore, the number that completes the pattern is the square root of 324, which is 18.
