Explain the Fibonacci sequence


assistant
The Fibonacci sequence is a sequence of numbers, where each number is the sum of the two numbers before that number. The Fibonacci sequence usually starts with zero followed by one. The next number in the sequence is then the sum of the preceding numbers, one and zero, which is one again. The following number is the sum of one and one: two. According to the same logic, the first ten numbers of the Fibonacci sequence are: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34.
