Maths - Choose-Your-Own Fibonacci Series Generator


This page allows you to generate a sequence similar to the classic Fibonacci series, but by setting different starting points you can investigate how the results differ.
You may choose between a numbered list, or an unformatted sequence of results. Both will have exactly the same entries. Please note that beyond about 200 values, the numbers displayed will start to get too long to display on a single line. The 'numbered list' result style is therefore formatted to allow the lines to wrap; the 'simple list' style displays unformatted numbers that can more easily be used in other software.


The Fibonacci sequence can be defined as: n[x] = n[x-1] + n[x-2]:
Where: n[1] & n[2] can be any value, including negative values.
and: x is the current element number, or 'index'


If you change the 'Number of entries to generate' box, after a list has been generated, the original list will be expanded from where it previously finished.
If you have a very old computer, and choose to calculate a long list, the system may become temporarily unresponsive. If this proves problematic, choose a small number first, then increase gradually. Only new values will be created each time.
