A golf ball dropped onto a hard surface rebounds exactly 1/3 of the height from which it falls. How far will it rebound after hitting the surface for the third time if it is initially dropped from height of 18m?? (please help!)

2/3m

if the ball drops 1/3 of 18m it implies that 1/3*18=6m
now the ball then rebounds back to the surface at the same assumed 1/3 hence 1/3*6=2
and for the third and final time 1/3* 2= 2/3m
