Answer:
The sum to infinity of the geometric series is;
[tex]S_{\infty}=720[/tex]Explanation:
Given an infinite geometric series where;
[tex]\begin{gathered} a_1=180 \\ r=\frac{3}{4} \end{gathered}[/tex]Recall that the sum to infinity of a geometric series can be calculated using the formula;
[tex]S_{\infty}=\frac{a_1}{1-r}[/tex]substituting the given values;
[tex]\begin{gathered} S_{\infty}=\frac{a_1}{1-r}=\frac{180}{1-\frac{3}{4}}=\frac{180}{\frac{1}{4}}=180\times4 \\ S_{\infty}=720 \end{gathered}[/tex]Therefore, the sum to infinity of the geometric series is;
[tex]S_{\infty}=720[/tex]
