About the Golden Ratio
The golden ratio (phi, approximately 1.6180339887) is an irrational number that appears throughout nature, art, and mathematics. As the Fibonacci sequence progresses, the ratio between consecutive numbers converges to this value. This is because each Fibonacci number is the sum of the two preceding ones, creating a ratio that stabilizes at phi.
