Prove: The square of the sum of
two consecutive integers is odd.

Step-by-step explanation:
To prove this statement.
Let's take an example:
1^2 + 2^2
=> 1 + 4 = 5
=> 5 = odd number.
We first took two consecutive integers 1, and 2. Then, we squared both the numbers to get 1 and 4. Lastly, we added these numbers to get 5, which is a odd number.
Another example:
-9 + (-10)
=> -9^2 + (-10)^2
=> 81 + 100
=> 181 = odd number
So this statement is correct.
