Using The Fibonacci Sequence To Look At Evolution! - Science Friday
WEBSep 6, 2018 · For any Fibonacci sequence, Fn will always be equal to (n-1) + (n-2). For example, let’s look at a Fibonacci sequence starting with 75, 120, 195. To find the next number in this sequence (Fn), you can add 120 (that’s the n-2) to the 195 (the n-1) to get 315 (the Fn). So the sequence is now is 75, 120, 195, 315. You now have a Fibonacci ...
