This isn't really a homework question so feel free to move is somewhere else. My teacher tried to explain this to me but I didn't understand it so I thought I'd try hearing another person's point of view.(adsbygoogle = window.adsbygoogle || []).push({});

The question is

lim n->infinity (2n-1)/(3n+1)

The working out I was showed is

= lim n->infinity (2n+2/3)/(3n+1) - (1 2/3)/(3n+1)

= 2/3 - 0 = 2/3

What I don't understand is how to work out that the lim n->infinity (2n+2/3)/(3n+1) is 2/3. We were shown rules for limits as n tends to infinity but I don't think I've come across the above situation before.
