A ball is droped from a height of 16 m on each bounce, it rebounds 0.5 of the distance it fell how far has the ball traveled. When it hits the ground for the fifth term?

Be more careful where you put your periods and capitalized letters. "How" starts your question and should be capitalized. "When" does not.
You probably meant:
How far has the ball traveled when it hits the ground for the fifth time?
The answer is
16 + 2*8 + 2*4 + 2*2 + 2*1 = 46 m
