If you were to draw a line starting in the right bottom corner of a golden rectangle within the first square and then touch each succeeding multiple squares outside corners, you would create a Fibonacci spiral. The closer the sections are to equal numbers, the closer they are to the golden ratio., 2023 Minute Media - All Rights Reserved. And I need to implement a function so that each subsequent call will output the next number in the sequence. Its history goes back over 2,000 years and is . When using the Fibonacci scale for relative sizing, teams experience the following benefits: Establishes a scale for comparing an item's complexity, uncertainty, and effort.
