Diverge means separate, converge means meet.

converge is to "settle down" on a finite falue

oh jeez, an algebra2 definition of "diverge" ? I kind of would like to know the context

heres what the question is 1/5+1/25+1/125+1/625... Does the infinite geometric series converge or diverge?explain

Does it go to infinity?

Or does it go to a specific value?

or does it settle on no value at all and oscillate forever?

Algebra 2 is an interesting time to learn about this. You should at least see the formal definition, so here's that (in my words): A sequence \(a_n\) converges to a limit \(L\) iff for any given \(\epsilon\), there exists an \(N\) such that \(n>N\implies a_nL<\epsilon\). That's the formal one. In english, that means, as you go on to infinity, the sequence gets as close as you like to a given value. Basically, like others have said, the sequence "settles down" to a value. Diverges simply means "does not converge."

it goes infinitly

Monkeyball Group TitleBest ResponseYou've already chosen the best response.1
no it does not.....the reason being that the denominator is getting bigger which means that the overall number is getting smaller.

@nbouscal I wish they taught me that in algebra2, but I don't think so...

If it went to infinity then the sequence will increase exponentially

Oh no, I'm sure they don't. They would never do something crazy like teach real mathematics to secondary school students :P

Not saying I know pedagogy better than they do, but couldn't they at least flash it on the board? One slide of a powerpoint? No? *sigh* oh well.

\[\sum_{n=1}^\infty ar^{n1}=\sum_{n=0}^\infty ar^n=\frac a{1r}\]is maybe a formula you can use?

TuringTest Group TitleBest ResponseYou've already chosen the best response.2
the above is only true for \(r<1\), otherwise the series diverges so you must identify }r in your series

is it 1/5?

nbouscal Group TitleBest ResponseYou've already chosen the best response.1
Yes, r=1/5

petegutz Group TitleBest ResponseYou've already chosen the best response.0
so it converges and it has a sum right?
