Answer:
r= 
Step-by-step explanation:
The sum to infinity of a geometric series is calculated as
S∞ =
; | r | < 1
where a₁ is the first term and r the common ratio
here a₁ = 15 and S∞ = 45 , then
45 =
( multiply both sides by (1 - r ) )
45(1 - r) = 15 ( divide both sides by 45 )
1 - r =
=
( subtract 1 from both sides )
- r =
- 1 = -
( multiply both sides by - 1 )
r =
