The third term of a geometric sequence is \( 3 \) and the common ratio is \( 3 \). Find the \( n \)th term.
\( a_n=3^{n-2} \), \( n\in\mathbb{N} \)
\( a_n=3^{n-1} \), \( n\in\mathbb{N} \)
\( a_n=3^{n} \), \( n\in\mathbb{N} \)
\( a_n=\frac3n \), \( n\in\mathbb{N} \)
\( a_n=3n \), \( n\in\mathbb{N} \)
