About the Fibonacci Generator

Fibonacci Generator is treated here as a quantitative relation between Number of Terms and Find nth Term and Fibonacci Sequence, F - nth Term Value, Golden Ratio and F/F Ratio.

The calculator uses a multi formula configuration. Each reported value is read as a direct evaluation of the stored rules with the declared field formats and units.

Formula basis:
F(n) = F(n-1) + F(n-2)
F(0)=0, F(1)=1
φ = (1+sqrt5)/2 approximately 1.618

Interpret the outputs in the order shown by the result fields. Optional inputs affect only the outputs that depend on those variables.

Formula & How It Works

The calculation applies the following relations exactly as recorded in the metadata:

F(n) = F(n-1) + F(n-2)
F(0)=0, F(1)=1
φ = (1+sqrt5)/2 approximately 1.618

Each output field is produced by substituting the supplied inputs into the relevant relation and then applying the declared rounding or text format.

Worked Examples

Example 1: First 10 Fibonacci Numbers

Inputs

n_terms: 10
Fibonacci Sequence: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34. F - nth Term Value: 55. Golden Ratio: 1.6180339887. F/F Ratio: 1.61764706. Sum of Sequence: 88

With Number of Terms = 10 as the stated inputs, the result is Fibonacci Sequence = 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, F - nth Term Value = 55 and Golden Ratio = 1.6180339887. Each value corresponds to the declared output fields.

Example 2: F(20) — 20th Fibonacci Number

Inputs

nth: 20
Fibonacci Sequence: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34. F - nth Term Value: 6,765. Golden Ratio: 1.6180339887. F/F Ratio: 1.61803396. Sum of Sequence: 88

With Find nth Term = 20 as the stated inputs, the result is Fibonacci Sequence = 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, F - nth Term Value = 6,765 and Golden Ratio = 1.6180339887. Each value corresponds to the declared output fields.

Example 3: Golden Ratio in Architecture

Inputs

nth: 13
Fibonacci Sequence: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34. F - nth Term Value: 233. Golden Ratio: 1.6180339887. F/F Ratio: 1.61805556. Sum of Sequence: 88

With Find nth Term = 13 as the stated inputs, the result is Fibonacci Sequence = 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, F - nth Term Value = 233 and Golden Ratio = 1.6180339887. Each value corresponds to the declared output fields.

Example 4: Fibonacci in Stock Charts

Inputs

n_terms: 8
Fibonacci Sequence: 0, 1, 1, 2, 3, 5, 8, 13. F - nth Term Value: 21. Golden Ratio: 1.6180339887. F/F Ratio: 1.61538462. Sum of Sequence: 33

With Number of Terms = 8 as the stated inputs, the result is Fibonacci Sequence = 0, 1, 1, 2, 3, 5, 8, 13, F - nth Term Value = 21 and Golden Ratio = 1.6180339887. Each value corresponds to the declared output fields.
