The term for a sequence of numbers in which each number is the sum of the two preceding ones is called the Fibonacci sequence. The sequence begins with the numbers 0 and 1, and each subsequent number is generated by adding the two previous numbers together. This pattern leads to a series that starts as follows: 0, 1, 1, 2, 3, 5, 8, 13, and so on. Fibonacci numbers are not only significant in mathematics but also frequently appear in nature, such as in the arrangement of leaves, the branching of trees, and the fruit sprouts of a pineapple.
