A child on a swing is let go from a vertical height so that the distance he travels in the first back - and - forth swing is exactly 9 feet.  If each swing decreases the distance by 85 % write a geometric series that expresses the distance the child travels in feet. 

• a_n = 9 (.85)^n-1

• a_n = 9 (.15) ^{n - 1}

• a_n = (.85) (9) ^n-1
