Maths revision

I have a test in less than a week for maths and was looking through an old test I had done. I found that my weakest point is proving something algebraically. The question was:
Prove algebraically that the difference between the squares of any two consecutive integers is equal to these two integers. I did try to attempt this question but completely sucked at it. :P any help is greatly appreciated many thanks :smile:

:smile:

if you have a number

n

then the next number is

n + 1

, the difference between the squares is

(n+1)^2 - n^2

Now make an equation relating to the addition of

n

and it's consecutive number and they should be equal for them to be the same.
