Example 1: Sum of Odd Numbers
By arranging dots in a square grid, you can see that the sum of consecutive odd numbers (1, 3, 5, 7,
9, 11) forms square numbers. For example, the sum of these odd numbers equals 36, which is the
square of 6. This pattern holds for any number of odd numbers, meaning the sum of the first 10 odd
numbers will also form a square.
