The general term of a sequence is given by \displaystyle t_n = \frac{5- n^2}{3n}, n \in \mathbb{N} 

a) Write the first five terms of this sequence.

b) Does this sequence have a limit as n \to \infty?

Q5

A bouncy ball is dropped from a height of 5 m. It bounces \frac{7}{8} of the height after each fall.

a) Find the first five terms of the infinite sequence representing the vertical height travelled by the ball.

b) What is the limit of the heights as the number of bounces approaches infinity?

c) How many bounces are necessary for the bounce to be less than 1 m?

Q6
