In Fibonacci's book one of the mathematical problems he investigated was how fast rabbits could multiply, assuming that they all survive of course. The background is that rabbits are placed in a field and can start breeding at one month each time bearing another pair. The dialogue dialog  goes like this...\\ \\  "At the end of the first month, they mate, but there is still only 1 pair.\\  At the end of the second month the female produces a new pair, so now there are 2 pairs of rabbits.\\  At the end of the third month, the original female produces a second pair, making 3 pairs in all.\\  At the end of the fourth month, the original female has produced yet another new pair, the female born two months ago produced her first pair also, making 5 pairs" (plus.maths.org).\\  \\  Notice that this problem has the makings of a Fibonaccie Fibonacci  sequence, see you can figure out what happens the fifth month.
