Binet’s Formula Calculator

To find the $n$-th Fibonacci number using Binet’s Formula, substitute $n$ into the formula and solve using the values of φ and ψ.

The Binet’s Formula Calculator is a tool that is developed to find any Fibonacci number without needing to go through all previous numbers in the sequence. Moreover, Binet’s formula provides a mathematical shortcut to obtain the $n$-th term directly.

This formula uses the golden ratio, denoted as φ, and its negative reciprocal, denoted as ψ. It is also worth-noting that it’s named after the French mathematician Jacques Philippe Marie Binet.

$n$Formula :

$$F_{n} = \frac{\phi^{n} - \psi^{n}}{\sqrt{5}}$$

How to Use Binet’s Formula:

1. Identify the nth term you want to find.
2. Apply the values of $\phi$ and the conjugate of $\phi$.
3. Plug these into the formula and simplify.

Solved Calculation:

Example 1:

Given: $n = 5$

Answer: The 5th Fibonacci number is 5.

Example 2:

Given: $n = 8$

Answer: The 8th Fibonacci number is 21.
