Question 1091854: How do I find out the limit of this equation?
n goes towards infinity and starts at zero. It didnt look nice when I tried to
write it in the equation
+sum%2880+%2A+%283%2F5%29%5En%29+

You can put this solution on YOUR website!
The sum +S+=+sum%28a%5B1%5Dr%5En%2C+n=0%2C+infinity%29++=+a%5B1%5D+%2F+%281-r%29+
For this problem, +a%5B1%5D+=+80+ and +r=%283%2F5%29+
so you can plug in and turn the crank for the answer.
