The Fibonacci sequence is a series of numbers where each number is the sum of the two preceding ones, starting from 0 and 1. So, the sequence begins as 0, 1, 1, 2, 3, 5, 8, and so on. This pattern appears in various aspects of nature, such as the arrangement of leaves on a stem or the spirals of a nautilus shell. The Fibonacci numbers are not just a mathematical curiosity; they also have applications in art, architecture, and even financial markets. The ratio of consecutive Fibonacci numbers approaches the Golden Ratio, which is often associated with aesthetically pleasing proportions in design and nature.
