Answer:
r = 0.8 of geometric series.
Step-by-step explanation:
Given : geometric series (1.3)([tex]0.8^{n-1}[/tex].
To find : What is the value of r of the geometric series
Solution : We have given that (1.3)[tex]0.8^{n-1}[/tex].
By geometric series formula [tex]a_{n}[/tex] = [tex]a_{1}r^{n-1}[/tex].
On comparison
[tex]a_{1}[/tex] = 1.3
r = 0.8
Therefore, r = 0.8 of geometric series.
