This program generates 𝜑, also called the golden ratio. It creates the fibonacci sequence \big\{1,1,2,3,5,8,13,\dots\big\} and divides the newly generated number by the last one. In theory this program would generate exactly [1] 𝜑.


Fibonacci sequence

  • \text{Start: }x_1=1\text{ and }x_2=1
  • \text{Generation: }x_n=x_{n-1}+x_{n-2}
  • 1+1=2
  • 1+2=3
  • 2+3=5
  • 3+5=8
  • 5+8=13
  • 8+13=\dots

The golden ratio (𝜑)

  • \phi\text{ is the ratio between }x_n\text{ and }x_{n-1}\text{.}
  • \phi=\frac{x_n}{x_{n-1}}
