Alright. Since these are squares, you need to write down the perfect squares you know…

1^2 = 1
2^2 = 4
3^2 = 9
4^2 = 16
5^2 = 25…and etc…

now that you know them… Try to look for two numbers thathave a difference of 7. only 3 and 4. But Since this is a positive number… the larger number should be a!!!

hope this helped
