# A ball is dropped from 1458 feet and at each bounce it rebounds 1/3 of the height from which it last fell. How far has the ball traveled by the time it strikes the ground for the sixth time? ⚑ Flag

I'm using an equation for the sum of a geometric sequence, but my answer is coming out wrong.  I know the answer should be 2910 feet, but I can't get that answer using the equation.

set up the function as D=Doe^-xt   when t=0 your D=Do=1458 then plug in  and D is 486 ( 1/3 of original height) when you have t=1 which is number of bounces solve for x, then plug in t=2,3,4,5,6 and find the height
