The third term of a geometric sequence is

9

and the common ratio is

3

. Find the recursive formula of the sequence.

a_{1} = 1

,

a_{n + 1} = 3 a_{n}

a_{1} = 3

,

a_{n + 1} = a_{n} + 3

a_{1} = 9

,

a_{n + 1} = 3 a_{n}

a_{1} = 3

,

a_{n + 1} = a_{n}^{2}

a_{1} = 1

,

a_{n + 1} = \frac{1}{3} a_{n}
