Instead of posting an idiotic message like "Get a TI-92," why not answer the
guys question. To do this on a 86, type:

seq(2x,x,1,4,1)
    and it will return
{2,4,6,8}.

Here is an explanation of the arguments for the function:
1st=expression
2nd=what the variable is
3rd=lower bound
4th=high bound
5th=step amount

Hope this helps
