Pell Series in JAVA

Pell Series

Pell Series : A series of numbers in which each number (Pell Number) is the sum of the twice the previous Pell number and the Pell number before that. It starts from 0 and 1.

 

The first few terms of the sequence are :-

 

0   1    2    5    12    29    70    169    408    985     

Program to Print Pell Series given below :-

Program :-

import java.io.*;
import java.util.*;
class Pell
{
    public static void main(String args[])
    {
        Scanner in = new Scanner(System.in);
        int a=0,b=1,c=0,n,i;
        System.out.println("Enter No. of terms");
        n= in.nextInt();
        System.out.println("Pell Series given below:-");
        System.out.print(a+"\t");//printing first number
        System.out.print(b+"\t");//printing second number
        for(i=3;i<=n;i++)
        {
            c=(2*b)+a;
            System.out.print(c+"\t");
            a=b;
            b=c;
        }
    }//end of main method
}//end of class
