The Fibonacci sequence, a series of numbers where each number is the sum of the two preceding ones (0, 1, 1, 2, 3, 5, 8, 13, 21, ...), has a profound connection to the golden ratio. As the sequence progresses, the ratio between consecutive Fibonacci numbers converges to Phi. This convergence is remarkably rapid, with the 40th Fibonacci number divided by the 39th already accurate to 15 decimal places.
