#### Answer

$\lim\limits_{n \to \infty}$ (3+5n^2)/(n+n^2) $\lim\limits_{n \to \infty}$ n^2((3/n^2)+5)/n^2((1/n)+1) = (0+5)/(0+1) =5 sequence converges on 5

#### Work Step by Step

take limit of sequence as n approaches infinity pull out n^2 from both the denominator and numerator cancel out n^2 $\lim\limits_{n \to \infty}$ (3/n^2) equals 0 because numerator is so small compared to denominator $\lim\limits_{n \to \infty}$ (1/n) also equals 0 because numerator is so small compared to denominator plug in numbers and solve
