Question: multiply sequence or a set of numbers

Hi, I am trying to have a sequence of (0,Pi/32,2Pi/32,3Pi/32...Pi)

Here is what I did : theta:=[seq((Pi/33).n,n=0..32]:

Question 1 : Is this the same as doing 0:Pi/32:Pi in matlab?

Question 2 : how do i select the output? for example output 5 which is 4Pi/32.

Question 3 : how do I multiply it with another sequence of (0,2,4,6,.......64)? for example to get a new set of numbers (0,2Pi/32,8Pi/32.....)

Please help. Thanks.
