The Fibonacci series is a sequence of numbers in which each number (after the first two) is the sum of the two preceding ones. The sequence typically starts with 0 and 1, although some variations start with 1 and 1. The mathematical definition of the Fibonacci sequence is:
With the initial conditions:
This means that:
So, the beginning of the Fibonacci series looks like this:
0, 1, 1, 2, 3, 5, 8, 13, 21, 34, ...
The Fibonacci sequence has many interesting properties and appears in various areas of mathematics and nature, such as in the branching of trees, the arrangement of leaves on a stem, the fruit sprouts of a pineapple, the flowering of an artichoke, and the arrangement of a pine cone.
java program sample code:
import java.util.Scanner;
public class Fibonacci {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.print("Enter the number of terms: ");
int n = scanner.nextInt();
scanner.close();
int a = 0, b = 1, c;
System.out.print("Fibonacci Series: " + a + " " + b);
for (int i = 2; i < n; i++) {
c = a + b;
System.out.print(" " + c);
a = b;
b = c;
}
}
}
