DiscretePlot

DiscretePlot[f,{n,nmax}] generates a plot of f as a function of n when n=1,…,nmax.

DiscretePlot[f,{n,nmin,nmax}] generates a plot when n runs from nmin to nmax.

DiscretePlot[f,{n,nmin,nmax,dn}] uses steps dn. 

DiscretePlot[f,{n,{n1,…,nm}}] uses the successive values n1, …, nm.

DiscretePlot[{f1,f2,…},…] plots the values of all the fi.
