How to assign an arithmetic series?

I am trying to have a difference of arithmetic series numbers between curves that I am arraying. Can the difference between the curves get an arithmetic series?

what do you mean by arithmetic series? Please be more specific.

The difference between consecutive curves should be in the order for example, 1,3,5,7,9 ansd so on respectively.
a,a+d,a+2d,a+3d…a+(n-1)d where ‘a’ is first term and ‘d’ is common difference.

Series?
