The Fibonacci sequence is a famous sequence of numbers that starts with 1 and 1, and each subsequent term is the sum of the previous two terms. For example, the first ten terms of the Fibonacci sequence are: 1, 1, 2, 3, 5, 8, 13, 21, 34, and 55. The sequence has many interesting properties and applications in mathematics, nature, art, and music. For example, the ratio of consecutive terms of the Fibonacci sequence converges to the golden ratio, which is approximately equal to 1.618. The golden ratio is considered to be aesthetically pleasing and can be found in many natural phenomena and artistic works.
