1.) First you have to write down your square numbers. Remember to only write the first couple of numbers because as square numbers get bigger the difference between them does.5 is a small number so only write the first couple numbers.
1,4,9,16,25
2.) Then you find the difference between each number.
25 - 16= 9
9 - 4 =5
4 - 1 =3
3.) look at which numbers have the difference of 5 and in this case it will be 9 and 4.
hope this helped.
