A bungee jumper falls meters and rebounds
of the distance after each fall.
(a)
\Find first five terms of the sequence.
\The infinite geometric sequence is .
Find the common ratio.
\The common ratio is
, then
.
The infinite geometric series has a sum.
\Find .
Here :
The sum of an infinite geometric series is
The first five terms of infinte sequence is
Include the up and the fall hence the sequence is .
