Answer:

3rd option

Explanation:

The sum to infinity of a geometric sequence is

S =
(a)/(1-r)

where a is the first term and r the common ratio

The expression inside the summation is

6
((1)/(3)) ^(n-1)

which is in the form of the nth term of a geometric sequence

with a = 6 and r =
(1)/(3) , then

S =
(6)/(1-(1)/(3) ) ← expression required

=
(6)/((2)/(3) )

= 9
