sequences and series

Hey guys I got a question on sequence and series.

A ball is dropped from a height of 1.2 m. If each time it bounces, it rebound to four fifth of the height of the preceding bounce, what is the total distance travelled by the ball after 8 bounces?????
I got 9.1894m but it doesn't look right.
Thanks guys.

1.2 + (1.92(1 - 0.8^7)/0.2 = 8.787
