Alright...so I'm not completely following. The f(1) does not cancel at the beginning. But what I'm asking is: If I use either r=n or r=n+1 at the end there will be something different that does not cancel either way. That is the f(n) and the f(n+1) term respectively. Which term to stop at when...
When using the method of differences on a given series, when do you stop listing the terms?
Example question:
f(r)= ; r∈N
State f(r)-f(r+1) in terms of r and hence determine
So skipping until the worked answer gives
Great so here I included the n+1th term because I'm guessing since the...
Ooooh! I understood what you were doing but not why you were doing it but it took me a couple minutes to completely get it. Thank you so much! I really appreicate your answer :)
So there's this question I've to do. I got through until a certain point and now I'm stuck. >->
1&2The question:

Its not that strange, honestly, it's just how it is. You see, my teacher rarely ever attends classes and when he does, he reaches sometimes twenty minutes before the bell rings and simply lectures us on life goals, the expectations of us, and talks about the country's state. He hardly teaches...
Fairly simple question I'd like someone to help with please. My teacher has me confused so I figured I'd turn to the forums for help.

I'm laughing because I joined the forums to ask questions but I've got none. :cry:
