Sorry for all the Geomtric Series Questions. I just find that its a hard topic to understand.
A ball is dropped from 405 meters and rebounds two-thirds the distance it falls each time it bounces. How many meters will the ball have traveled when it hits the ground the fourth time?
Thanks in advance 
+37191 First drop 405 meters then it goes up AND down 2/3 (405) = 270
second bounce goes up and down 2/3 270 = 180
third bounce up and down 2/3 180 = 120
405 + 2 (270) + 2(180 ) + 2(120) = ........m
