hi!

probably a very easy question, but i couldn't find an answer in the
mathematica-book:

i need to extract elements from a list, starting th element number x and
than taking every yth element, eg:

with

list={a,b,c,d,e,f,g,h,i,j}
start=3;
step=2:

i'd like to get the list

{c,e,g,i}.

how can i do this in the easiest way?

regards, robert
