    I'm having a hard time interpreting what you're asking...

    Do you mean \sum_{n=1}^{\infty}\frac{3n+7}{2n^2-n} or \sum_{n=1}^{\infty}\frac{2n^2-n}{3n+7}??

    After a combination of divination with the Math Gods and my uncanny ability to read completely incomprehensible math type this says

    \sum_{n=1}^{\infty}\frac{3n+7}{n^2-n}

    In which case it diverges by the limit comparison test

    \frac{3n+7}{n^2-n}\sim\frac{3}{n}
