\text{Hello! It looks like you have a question about predicting the rebound height of a ball. The information you've provided shows the ball starts at a height of 200 cm and gives the rebound heights for the first two bounces. However, there is missing information, and it seems the table is incomplete.}
\text{To help you further, I need to know:} \begin{enumerate} \item \text{The rebound ratio or the percentage of the height retained after each bounce.} \item \text{How many bounces you would like to calculate the height for.} \end{enumerate}
