Hi Guys,

I'm doing GCSE maths higher tier. And generally I'm quite good at algebra, subsitiution, factorising etc but I'd appreciate help with arguments.

Here is the question:

"Prove that the sum of squares of any two consecutive integers is an odd number".

It has to be done algebraically. I have the answers but I don't understand them, can you please describe how you get the answer, also

please can you provide general tips for answering these arguments mental approach, algebra etc. and the quicker the reply the better. I have a maths

exam and it's quite urgent, so all help will be appreciated.

Thanks,
