I came across the formular S=a/(1-r) in my notes but I can't figure out exactly what a and r are and how to find them. Can anyone explain?
 
Ah ok I get it now. Would you believe this is degree level? Although I mean that in the loosest sense of the word.

No this is a-level stuff, normal maths. Not even further maths.

This would be assumed knowledge in a degree.

If we are talking about a maths degree

Well luckily for me we aren't :p It was just an open option. I think I did it for A-level too. The unit I'm on doesn't go much beyond maths+further maths A-levels.

I can believe that you need this in a degree yes. What I cant believe is that you are doing a degree whilst not being resourceful enough to use google. How on earth do you normally look stuff up when you are confused?!

Well first port of call is lecture notes. It was used but not explained in those. Then I checked wikipedia and I couldn't find it explained on there. I tried googling it but it came up with completely useless results.

If you type "sum of a series" into google nearly every link on the first page has the answer in it :S. Oh well, I'll shut up.

Ok now I think about googling the actual formula probably wasn't the smartest idea :o Oh well if my brain was on top form at the moment I would have probably been able to remember it anyway.
