Hey everyone, I don't know if I'm posting in the right section, but anyways..I am pretty bad with converging series and I need help with these questions
Big thanks in advance!
Well I know that if a series diverges then it reaches infinity, the converges part I gotta look for the series which has a limit, I plugged in the n=1 into the equation
looking at the questions 1 (since its the easiest) the answer is C and D (right?) cause those two reaches a limit, I'm just a tad bit rusty for the rest of the questions, a lil tip would teach me a lot.
Then you "know" something that is not true! For example the series $\displaystyle \sum_{n=0}^\infty (-1)^n= 1- 1+ 1- 1+ \cdot\cdot\cdot$ neither converges nor "reaches infinity".
I can see no sense in say series converge "because they reach a limit" sinced that is the definition of "converge". How do you know they "reach a limit"?, the converges part I gotta look for the series which has a limit, I plugged in the n=1 into the equation
