Suppose h_{k}and r_{k}denote the number of hares and rabbis respectively in the year k.

Assume that the number of those hares and rabbits changes over the years according to the following rule:

r_{k+1}= 10r_{k}- 3h_{k}

h_{k+1}= 4r_{k}- 2h_{k}

If there are 2 hares and 100 rabbits initially, what is the number of hares and rabbits in 2 years? in 20 years?
