For every whole number there exists a greater whole number. Prove the statement by example; 44 is a whole number and 56 is a whole number, and is greater than 44. Therefore the statement is true. Im not sure how to start this please help

I have no idea what you mean by "prove by example". Was this given as part of the exercise or are you saying that you were trying to prove this statement "by example"? You cannot prove that, for any whole number there exist a larger number by showing an example. What you have shown "by example" is simply that there is a number larger than 44. You cannot prove any general statement "by example".

The mistake in the supposed proof is that it has not shown the claim is true for every whole number. It has only shown it is true for the number 44.
