Final answer:

The difference between two consecutive square numbers is always odd.

Step-by-step explanation:

To prove that the difference between two consecutive square numbers is always odd, we can use a simple mathematical proof. Let's consider two consecutive square numbers, n^2 and (n+1)^2. Taking the difference between them, we have:

(n+1)^2 - n^2 = n^2 + 2n + 1 - n^2 = 2n + 1.

We can see that the result is always of the form 2n+1, where n is an integer. Since an odd number is always of the form 2n+1, we can conclude that the difference between two consecutive square numbers is always odd.

The first square number can be represented by
n^(2)

The second square number can be represented by
(n+1)^(2)

Subtract them:


(n+1)^(2) - n^(2)

Expand it first:


n^(2) + 2n + 1 - n^(2)

Simplify:


2n+1

Anything multiplied by 2 is even. Adding 1 to this value would make it odd. This proves it.

Hope This Helps You!

Good Luck (:

Have A Great Day ^-^
