How can I use conditionals in Mathematica to check for multiples of 3?

[Niles]

Hi all

I'm am looking for a smart way to make the following conditional in Mathematica:

if[i == 3*{1,2,3,4,5,N}, ...]

,

ï.e. if the variable i is a multiple of 3 up to some integer N. How can I do this smartest in Mathematica?

Er, what are you asking?

How to make a conditional statement? Check the documentation for If. (Or the guide section on programming)

How to make a range of integers? Check the documentation for Table. (Or the guide section on lists and sequences)

Ok, my answers were both answered looking at the documentation. Thanks.
