Rabbit family problem.

pixel01

Dear all,

I have this interesting problem and have not settled it out.
There is a pair of rabbits which reproduce very fast. Every week the pair gives birth to a new rabbit pair. Baby rabbits will be able to reproduce whey they were 4 weeks old. So after 52 weeks, totally how many rabbit pairs are there if no rabbits die and the first pair of rabbits still reproduce.

(Hope this thread is suitable in this box)

Thanks
