Tribonacci Series in JAVA

Tribonacci Series

Tribonacci Series : A Tribonacci sequence is a sequence of numbers such that each term from the fourth onward is the sum of the previous three terms.

It is similar to Fibonacci Series

 

The first few terms of the sequence are :-

 

0, 0, 1, 1, 2, 4, 7, 13, 24, 44, 81, 149, 274, 504, 927

Program to Print Tribonacci Series given below :-

Program :-

import java.io.*;
import java.util.*;
class Tribonacci
{
    public static void main(String args[])
    {
        Scanner in = new Scanner(System.in);
        int a=0,b=0,c=1,d=0,n,i;
        System.out.println("Enter No. of terms");
        n= in.nextInt();
        System.out.println("Fibonacci Series given below:-");
        System.out.print(a+"\t");//printing first number
        System.out.print(b+"\t");//printing second number
        System.out.print(c+"\t");//printing third number
        for(i=4;i<=n;i++)
        {
            d=a+b+c;
            System.out.print(d+"\t");
            a=b;
            b=c;
            c=d;            
        }
    }//end of main method
}//end of class
