Fibonacci sequence

The Fibonacci sequence is a sequence of numbers in which each number is the sum of the two preceding numbers. The sequence starts with 0 and 1, and continues as follows:

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, 1597, 2584, 4181, 6765, 10946, 17711, 28657, 46368, 75025, 121393, 196418, 317811, ...

To obtain each term of the sequence, you add the two previous terms. For example, to obtain the third term, you add the first and second terms:

0 + 1 = 1

To obtain the fourth term, you add the second and third terms:

1 + 1 = 2

And so on.

The Fibonacci sequence has many interesting properties and is found in many natural phenomena, including the growth patterns of plants and the arrangement of leaves on stems. It also arises in many areas of mathematics, including number theory, algebra, and combinatorics.
