The Fibonacci sequence, also known as the golden section sequence, refers to a sequence of numbers: 0, 1, 1, 2, 3, 5, 8, 13, 21, ... In mathematics, the Fibonacci sequence is defined recursively as follows: F0=0, F1=1, Fn=F(n-1)+F(n-2) (n>=2, n∈N*) In modern physics, quasi-crystal structure, chemistry and other fields, the Fibonacci sequence has direct applications. For this reason, the American Mathematical Society has published a mathematics magazine named "Fibonacci Sequence Quarterly" since 1963, which is used to publish research results in this area.

The Fibonacci sequence refers to a sequence of 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, ...

Special note: 0 is the 0th term, not the 1st term.

Starting from the second term, each term in this sequence is equal to the sum of the previous two terms.

The inventor of the Fibonacci sequence is the Italian mathematician Leonardo Fibonacci.
