macro to copy columns and paste into another sheet

[beginner]

I have over 120 columns on one sheet and I would like to copy and
paste every 3rd column onto another sheet. I started to "record"
macro, but was wondering if there was a way to write code for this?

so I have something like this:

x y z x y z
x y z ...............................
1
1
2
3
8
7,etc..

I would like to copy all of the "x" column values onto another sheet.
Any solutions?

Thanks!
