I have already posted this question but I accidentally asked for the nature of the 'series', where as I wanted someone to help me with,

how I can tell if the following sequences {a_{n}} diverge or converge? And how to justify it?

Hey calmo11.

The first thing you should do is list the type of series (alternating, non-alternating in sign) and list the different kinds of tests for that particular series. Can you do this to start off with? - April 16th 2013, 06:35 PMSorobanRe: Nature of the sequence

If the limit is finite, the sequence converges.

We see that: .

The sequence converges.

Quote:

Divide numerator and denominator by

Then: .

The sequence converges.

Multiply by

Then: .

The sequence converges.
