Context provision might help better. Thank you.

Answer 1

It would've been helpful if you gave exactly what you have in mind 

I think "This model is a  series of order  1" is the correct form, although I personally prefer "This model is a first order series"

However, as I said it depends on what you have in mind. I mean in Persian.
