Pls, someone should kindly help with this problem.Show that (3n)/(n+2) tends to 3 as n tends to infinity.

Is there any restriction on method of demonstration?

What have you tried? Where did you get stuck?

D only one I can deal with is wen n tends to real number not infinity.

\(\displaystyle \dfrac{3n}{n+2}=\dfrac{3}{1+\dfrac{2}{n}}\)

I can deal with [it when] n tends to [a] real number

Okay, what happens when you make that number bigger and bigger?

Also, are you trying to be cute with English? :-?
