A man put a pair of rabbits (a male and a female) in a garden that was enclosed. How many pairs of rabbits can be produced from the original pair within 12 months, if it is assumed that every months each pair of rabbits produce another pair (a male and a female) in which they become productive in the second month and no death, no escape of the rabbits and all female rabbits must reproduced during this period (year)?

The solution to this problem has a certain sequence of numbers, which today is known as Fibonacci numbers or Fibonacci sequence [3]. The (figure 1.0) shows the representation of how the rabbits reproduced
