Sequence |
---|
A Sequence is an ordered list of numbers. |
Below are three examples of sequences:
-2, 5, 8, 15, 20
-21, -18, -7, 7, 8
1, 2, 3, 5, 7, 9, 10
The Fibonacci Sequence |
---|
The Fibonacci Sequence is an ordered list of numbers where each new term is the sum of the two previous terms. |
Below is the beginning of the Fiboacci Sequence:
1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89…

Above, you can see how each new term comes from the sum of the two previous terms.
The Fibonacci Sequence is an example of a recursive formula.
Recursive Formula |

In a recursive formula, each new term is formulated from one or more previous terms. |
