A sequence of numbers, created by Leonardo of Pisa (also known as Fibonacci). The sequence starts out with the first two numbers being 0 and 1, and after that you add the previous two numbers to get the next number in the sequence. Often used in proofs.

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, 1597, 2584, 4181, 6765

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, 1597, 2584, 4181, 6765

The fibonacci sequence starts with 0, 1....

0+1=1, so the next number must be 1.

1+1=2, so the next number is 2.

2+1=3, and so the next number is 3, and so on.

0+1=1, so the next number must be 1.

1+1=2, so the next number is 2.

2+1=3, and so the next number is 3, and so on.
