The sequence "0, 1, 1, 2, 3, 5, ..." is known as the Fibonacci sequence. Each number in the sequence is the sum of the two preceding numbers. It starts with 0 and 1, and then continues as follows: 0 + 1 = 1, 1 + 1 = 2, 1 + 2 = 3, and so on. This sequence appears in various areas of mathematics and nature. For example, it can be found in the arrangement of leaves on a stem, the branching of trees, and the patterns of some flowers. The Fibonacci sequence is also used in computer algorithms and financial markets.
