redict the general term or nth term, $$ a_{n} $$, of the sequence. $$ \begin{array}{ll}	ext { 9. } 1,3,5,7,9, \ldots & 	ext { 20. } 3,9,27,81,243 	ext {, } \ 	ext { 1. } \sqrt{2}, \sqrt{4}, \sqrt{6}, \sqrt{8}, \sqrt{10}, \ldots & 	ext { 22. } 1.2,2.3,3.4,4.5\end{array} $$

1. Sequence 9: $$ a_n = 2n - 1 $$ 2. Sequence 20: $$ a_n = 3^n $$ 3. Sequence 1: $$ a_n = \sqrt{2n} $$ 4. Sequence 22: $$ a_n = n + 0.2 $$

redict the general term or nth term, \( a_{n} \), of the sequence. \( \begin{array}{ll}\text { 9. } 1,3,5,7,9, \ldots & \text { 20. } 3,9,27,81,243 \text {, } \\ \text { 1. } \sqrt{2}, \sqrt{4}, \sqrt{6}, \sqrt{8}, \sqrt{10}, \ldots & \text { 22. } 1.2,2.3,3.4,4.5\end{array} \)
