Use summation notation to express the given infinite series.
\[ \frac3{x^3}+\frac3{x^2}+\frac3x+3+3x+\dots \]
\( \sum\limits_{n=1}^{\infty}3\cdot x^{n-4} \)
\( \sum\limits_{n=1}^{\infty}3\cdot x^{n-3} \)
\( \sum\limits_{n=1}^{\infty}3\cdot x^{n+3} \)
\( \sum\limits_{n=1}^{\infty}3\cdot x^{n+4} \)
\( \sum\limits_{n=1}^{\infty}3\cdot x^{n} \)
