Golden Ratio & Fibonacci Sequence
Golden Ratio & Fibonacci Sequence There is a special relationship between the Golden Ratio and the Fibonacci Sequence: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ... (The next number is found by adding up the two numbers before it.) And here is a surprise: when we take any two successive (one after the other) Fibonacci Numbers, their ratio is very close to the Golden Ratio . In fact, the bigger the pair of Fibonacci Numbers, the closer the approximation. Let us try a few: A B B/A 2 3 1.5 3 5 1.666666666... 5 8 1.6 8 13 1.625 ... ... ... 144 233 1.618055556... 233 377 1.618025751... ... ... ... We don't even have to start with 2 and 3 , here I chose 192 and 16 (and got the sequence 192, 16, 208, 224, 432, 656, 1088, 1744, 2832, 4576, 7408, 11984, 19392, 31376, ... ): A B B / A 192 16 0.08333333... 16 208 13 208 224 1.07692308... 224 432 1.92857143... ... ... ... 7408 11984 1.6
