help with the last part of the question (the odd and even thing).

 

[math man]

you should of worked out from iii) that:



now these are the first 2 odd terms of the sequence, if you look at what the question wants you to prove, you can then realise that:



then you can say, therefore for n is odd (n+1)I is blah blah...

and then i reckon you can finish the even off, exact same setting, but with the even members...hope this helps

Edit: Probably best to say then we can deduce is blah blah...therefore continuing this pattern will lead to:

equals blah blah for n is odd
