Finding Values of p for Convergence: (-1)^(n-1)/ n^p

[remaan]

Homework Statement

For what values of p is the series con.
(-1)^ (n-1)/ (n)^(p)

Homework Equations

In order for a p series to converge, p should be greater than 1

The Attempt at a Solution

So an = 1/ n^p

and p > 1

Is that right ?

I don't think so,, the only abbreviation is Con. which means Convergent

** Am trying to find the valu of p for which the series will converge

What I thought about is : becauce it 's a p-series , then p should be P greater than 1 ?

What do you think ??

 

[Hurkyl]

becauce it 's a p-series

No it's not.

So, give a hint? !

Oh, you I mean this part is a p- series, the one I considered as an
