Rabbit Problem       

Hare is the problem.  How many rabbits would you have  at the beginning of each month if you start with a single pair and ( condition one) each adult pair gives birth to a new pair every month;  ( condition two) each pair reproduces from the second month on and ( third condition) no rabbit dies; determine the number of rabbits after seven months.

Suggest that you make a diagram  of the number of rabbits that exist for each of the seven months.
