3 "The difference between any two square numbers is always odd."
Disprove this statement by means of a counter example.
Answer
One way to find a counter example is to start by listing the first few square numbers
1, 4, 9, ...
Then look at different combinations of their differences to see if any give an even
number
9 - 1 = 8 which is even, so it is not true that the difference between any two square
numbers is always odd
