Question: Please Help...I do not know what I am doing

I have been given the logistics map:   x_n+1 = rx_n(1-x_n) where x_n is a number between zero and one that represents the size of the population in the nth generation as a ratio of the environment’s maximum capacity.
The parameter r is a positive number related to both the reproduction rate and the rate at which the
population dies due to limited resources.  Create a procedure (taking arguments r and initial population size x₀)that returns the list [x₀, x₁, x₂, . . . , x₉₉] where the x₀ is the initial population size, x₁ is the population size after 1 generation....ect ect...   I understand that at each iteration, the current population is changed by the equation, and the next iteration uses it; however, I am very new to Maple and haven't a clue how to set this up.

Any help would be appreciated
