I need to show that the limit of the sequence,

is e-1. What's sad is I have the solution in front of me and I can't understand the simple algebra.

The second factor on the left, how did they get that?

One "n" in the denominator of the left factor was taken inside the brackets.

and the rest follows.

Do you understand how the first term and common ratio of the geometric series,

were placed into the formula for summing the series ?

I think I misread your question a little.

It is of course a "series", rather than a sequence. - June 28th 2011, 06:04 PMzg12Re: limit of sequence

It may have been offputting to see "n" as the term in the numerator and denominator

as it is also the number of terms in the series.
