If, using the direct comparison test, I compare each of the series listed below to $~~\displaystyle\sum\limits_{n=1}^{\infty }~{\frac{n^2}{2n^2+3}}\,$, what can I conclude? I. $\qquad\displaystyle\sum\limits_{n=1}^{\infty }{\frac{n^2}{2n^2+4}}$ [[☃ radio 1]] II. $\qquad\displaystyle\sum\limits_{n=1}^{\infty }~{\frac{2n^2}{2n^2+3}}$ [[☃ radio 2]] III. $\qquad\displaystyle\sum\limits_{n=1}^{\infty }~{\frac{n}{2n^2+3}}$ [[☃ radio 3]]
