Can Someone Please Help Me On This Grade 11 Math Of Personal Finance Problem?

A ball is dropped from a height of 10m. After each bounce, it reaches half of its previous height.

2. determine the formula to calculate the height after the nth bounce.
3. what is the height after the 8th bounce?
I’m trying to figure out if i am doing it the right way or not. I’m having problems figuring out the n-th way. Please help!
