Answer :

ANSWER

Converges

[tex]S_{ \infty } = 68[/tex]

EXPLANATION

The guy sequence is

17 + 12.75 + 9.5625 + ...

The common ratio is:

[tex] \frac{9.5625}{12.75} = \frac{12.75}{17} = \frac{3}{4} = r[/tex]

Since

[tex] |r| < 1[/tex]

the series converges.

The sum to infinity of this sequence is :

[tex]S_{ \infty } = \frac{a}{1 - r} [/tex]

where a=17 is the first term of the series.

[tex]S_{ \infty } = \frac{17}{1 - \frac{3}{4} } [/tex]

[tex]S_{ \infty } = \frac{17}{ \frac{1}{4} } = 68[/tex]
