What Is the Fibonacci Sequence?
The Fibonacci sequence is a series of numbers where each number is the sum of the two preceding ones, starting with 0 and 1: 0, 1, 1, 2, 3, 5, 8, and so on. It’s defined by the recurrence relation F(n) = F(n-1) + F(n-2), with F(0) = 0 and F(1) = 1.
Our Fibonacci Sequence Calculator generates the n-th Fibonacci number or the sequence up to the n-th term (n ≤ 1000) using BigInt for precision, with bar chart or spiral visualizations. Try it now!
