What Are Limits and Convergence of Infinite Sequences?

Ryan bounces a basketball, at its highest point the ball reaches 25ft. From that point the ball rebounds to 0.75 of its previous height. Let $h_n=$the high point of the nth bounce. Let the initial bounce, $h_0=25ft$. Consider the height of the ball after 10 bounces, 20 bounces, and 50 bounces. What conjecture can be made about the limit of the sequence?
