The ratio is common, so you could write:
a1 * r^4 = a^5 (you do r^4 because there are 4 times you need to multiply by the ratio to get from a1 to a5)
Plug in the values:
3 * r^4 = 48
Divide by 3:
r^4 = 16
Take the fourth root of both sides:
r = 2
The common ratio is 2.
(x-9)(x+7)=0
x-9=0 or x+7=0
x=9 or x=-7
:)
The answer will turn out to be 26.87
I think the answer 5 over 2
