Haven't done simultaneous equations.. and we weren't taught to guess. Our teacher taught us differences. I've got to log off, but if you could post more questions I'd attempt them later and see if I can answer them. If not , I might have to learn about your other methonds.
Thanks for the help

Haven't learnt curve fitting. Differences , I'm assuming is find the difference between the first two terms and that becomes your N then you find what you have to subtract or add to make the equation work?
(I can't solve number 1, whats the answer?)

I can't seem to find the answer to 1...
Any tricks on solving these?

Hi ZainH
3) Is correct! As far as correct means in this context.
Sorry but 1 is wrong.
Is 3) the only correct one? Or were you just mentioning that because the other two were sort of obvious.
And not sure what you meant by "As far as correct means in this context"

Ahh..
3. N^3 - 1

1. 6n-1
2. 8n-2
Give me a little more time on the 3rd one.

Not sure of the exact name but its for IGCSE grade 9.
And expanding questions like.. a(x+y) = ax+ay. But thats wayy to simple, throw in some numbers, squares, cubes, more variables, etc.
No idea what factoring of quadratics are... I wish I had my textbook right now. How about the nth term? Just give a few numbers and Ill try to find the next one.

Hey everyone, this is my first post and I decided I need some help with a coming up math exam. Not something as big as a final, but I still need to get good grades. Unfortunately I forgot my math textbook in my locker and its the weekend, so I was wondering if anyone could maybe give me some questions to work on either from some website they use or a textbook. Questions about the Nth term and expanding and factorizing algebraic equations. Not too complex but not too simple either ;) . Thanks tons.
