Answer:

Therefore 9th term of the geometric sequence is
(2)/(2187)

Explanation:

Given first term(a) = 6

and common ratio =
(1)/(3)


T_n= ar^(n-1)


\therefore T_9=ar^(9-1)


\Leftrightarrow T_9=a r^8


\Leftrightarrow T_9=6* ( (1)/(3)) ^8


\Leftrightarrow T_9=(2)/(2187)

Therefore 9th term of the geometric sequence is
(2)/(2187)
