How do you find the sum of the infinite geometric series 1-1/2+1/4+1/8?
As Alan P. indicated, this question has to be modified. I'm gonna assume that it is
First you must find r, the common ratio.
You find this with the following formula: r =
r = #(-1/2)/1)
The ratio is therefore
Find the sum of the following infinite geometric series: 2,
#6/5#, #18/25#, ...
Assume that a pendulum swings forever. The second swing measures 63 cm. The pendulum's distance diminishes by a third each time. Find the total distance covered by the pendulum rounded to 3 decimals.
