calculus - How do I calculate/prove limits for exponential functions: limlimitsnrightarrowinftyfrac2n+1+3n+12n+3n=3



How do I formally prove that lim. I calculated a few results so I am quite sure that the limit is 3, but I'm struggling on how to do calculate/proof that correctly.


Answer



=\frac{2(\frac{2}{3})^n+3}{(\frac{2}{3})^n+1}
