Tawfik Mohammed notes that 13, considered by some to be an unlucky number, is found at position number 7, the lucky number! The Fibonacci Sequence and Gambling or Lotteries The ratio of successive Fibonacci numbers converges on phi Then you can use this formula, discovered and contributed by Jordan Malachi Dant in April 2005:īoth approaches represent limits which always round to the correct Fibonacci number and approach the actual Fibonacci number as n increases. Perhaps a better way is to consider 0 in the Fibonacci sequence to correspond to the 1st Fibonacci number where n = 1 for 0. If you consider 0 in the Fibonacci sequence to correspond to n = 0, use this formula: Here are two ways you can use phi to compute the nth number in the Fibonacci sequence (f n). Ĭompute any number in the Fibonacci Sequence easily! After the 40th number in the sequence, the ratio is accurate to 15 decimal places. The table below shows how the ratios of the successive numbers in the Fibonacci sequence quickly converge on Phi. This relationship wasn’t discovered though until about 1600, when Johannes Kepler and others began to write of it. The relationship of the Fibonacci sequence to the golden ratio is this: The ratio of each successive pair of numbers in the sequence approximates Phi (1.618.), as 5 divided by 3 is 1.666…, and 8 divided by 5 is 1.60. This sequence is shown in the right margin of a page in Liber Abaci, where a copy of the book is held by the Biblioteca Nazionale di Firenze. ![]() Starting with 0 and 1, each new number in the sequence is simply the sum of the two before it.Ġ, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377. ![]() He is also known as Leonardo Bonacci, as his name is derived in Italian from words meaning “son of (the) Bonacci”. This sequence was known as early as the 6th century AD by Indian mathematicians, but it was Fibonacci who introduced it to the west after his travels throughout the Mediterranean world and North Africa. In the 1202 AD, Leonardo Fibonacci wrote in his book “Liber Abaci” of a simple numerical sequence that is the foundation for an incredible mathematical relationship behind phi. Leonardo Fibonacci discovered the sequence which converges on phi.
