Trying to write a series: 2n+1

I'm trying to write a 2n+1 series that starts at the number 2 and goes for 30 terms. How can I do this?

This sounds an awful lot like homework. What have you tried so far? Please read the Getting started part of the documentation.

How about a loop?

It would work without a FOR loop also, if it works at all. Usually "n" is a natural number in problems related to series. But there is no natural number n such that 2*n+1 equals 2.

hi, try this :

 % Sol1 : vectorized
 serie1=2*[2:30]+1;   figure, plot(serie1);

 % Sol2 : loop
 for x=2:30
   serie2(x)=2*x+1;
 end
 serie2(1)=[]; figure, plot(serie2)

Please, Youssef, do not post full answers for homework questions. Thanks.
