Marcus dropped a ball from a height of 400 cm. The sequence below shows the height of the ball, in cm, during its first four bounces. 240, 144, 86.4, 51.84, ... Which formula could be used to determine the height of the ball after n bounces? Ah(n) = 400(0.60)" 8 h(n) = 400(0.60)(n-1) C (n) = 240(0.60) Dh(n) = 240(0.60)(n-1)​
