Rails: how to find record before last?

Question

I can find last record in my table like in example below, but what if I want to find record before last, e.g. (last-1) or (last-2)..? I have this example in my each loop:

Answer 1

Table.where(:dogovor_id => p.id).order("id DESC").first           # last
Table.where(:dogovor_id => p.id).order("id DESC").offset(1).first # last - 1
Table.where(:dogovor_id => p.id).order("id DESC").offset(2).first # last - 2
