fibonacci series in Ruby


The Fibonacci Sequence is the series of numbers:
0, 1, 1, 2, 3, 5, 8, 13, 21, 34, ...
The next number is found by adding up the two numbers before it.
  • The 2 is found by adding the two numbers before it (1+1)
  • Similarly, the 3 is found by adding the two numbers before it (1+2),
  • And the 5 is (2+3),
  • and so on!
