by

In the previous article we have discussed about Java Program to Print the Series 1 -2 6 -15 31 …N

In this article we are going to see how to print the series 10 5 60 15 110 …..N by using Java programming language.

Java Program to Print the Series 10 5 60 15 110 …..N

On observing the pattern carefully, we can see 1st and 2nd number are 10, 5 respectively

Then the next number follows a logic

10
5
10+50 = 60
5+10 = 15
60+50=110
15+10=25 and so on.
10 5 60 15 110 25 … N

Let’s see different ways to print the series 10 5 60 15 110 …..N

Method-1: Java Program to Print the Series 10 5 60 15 110 …..N By Using For Loop

Approach:

  • Create Scanner class object.
  • Declare an integer variable say ‘n’ which holds the Nth term of the series.
  • Prompt the user to enter a number as value of n.
  • Let declare integer variable say ‘x’,’y’ and initialize it to 10,5 respectively.
  • Use a for loop from i=1 to i<=n where the loop is incremented by 1
  • Inside the for loop we will first check the position of the nth term If the position is odd then add 50 with ‘x’ else add 10 with ‘y’
  • Print the result in the series.

Program:

import java.util.*;
public class Main
{
    public static void main(String [] args)
    {
        //creating object of Scanner class 
        Scanner s = new Scanner(System.in);
        //Taking input of number of elements in the series
        System.out.println("Enter the Nth term “N” ");
        int n = s.nextInt();
        int x = 10, y=5;
        //for loop to print the series
        for(int i=1;i<=n;i++)
        {
            if(i%2!=0)
            {
            	System.out.print(x+" ");
            	x+=50;    
            }
            else
            {
            	System.out.print(y+" ");
            	y+=10;
            }
        }     
    }
}

Output:

Enter the Nth term “N” 
5
10 5 60 15 110

Method-2: Java Program to Print the Series 10 5 60 15 110 …..N By Using While Loop

Approach:

  • Create Scanner class object.
  • Declare an integer variable say ‘n’ which holds the Nth term of the series
  • Prompt the user to enter a number as value of n.
  • Let declare integer variable say ‘x’, ‘y’ and initialize it to 10, 5 respectively
  • Declare and initialize an integer variable i=1
  • Continue a while loop till i<=n, where i is incremented by 1.
  • Inside the while loop we will first check the position of the nth term If the position is odd then add 50 with ‘x’ else add 10 with ‘y’
  • Print the result in the series.

Program:

import java.util.*;
public class Main
{
    public static void main(String [] args)
    {
        //creating object of Scanner class 
        Scanner s = new Scanner(System.in);
        //Taking input of number of elements in the series
        System.out.println("Enter the Nth term “N” ");
        int n = s.nextInt();
        int i=1, x=10, y=5;
        while(i<=n)
        {
            if(i%2!=0)
            {
            	System.out.print(x+" ");
            	x+=50;    
            }
            else
            {
            	System.out.print(y+" ");
            	y+=10;
            }
            i++;
       }      
    }
}

Output:

Enter the Nth term “N” 
7
10 5 60 15 110 25 160

Method-3: Java Program to Print the Series 10 5 60 15 110 …..N By Using User Defined Method

Approach:

  • The same logic as method 1 but this time we are moving the for inside a user-defined method
  • Create a Scanner class object.
  • Prompt the user to enter the Nth term “N”
  • Call a user defined method printSeries() by passing n as parameter.
  • Inside the method use a for loop to find the series.
  • Let declare integer variables say ‘x’, ‘y’ and initialize it to 10,5 respectively
  • Use a for loop from i =1 to i<=n incremented by 1
  • Inside the for loop we will first check the position of the nth term If the position is odd then add 50 with ‘x’ else add 10 with ‘y’
  • Print the result in the series.

Program:

import java.util.*;
public class Main
{
    public static void main(String[] args)
    {
        // creating object of scanner class 
        Scanner s = new Scanner(System.in);
        //Taking input of number of elements in the series
        System.out.println("Enter the value of Nth term 'N' ");
        int n = s.nextInt();
        // calling printSeries method to print the series
        printSeries(n);
    }
    
    //printSeries metthod to print the series
    public static void printSeries(int n)
    {
        int x = 10, y = 5;
        //for loop to print the series
        for (int i = 1; i <=n; i++) 
        {
            if(i%2!=0)
            {
            	System.out.print(x+" ");
            	x+=50;    
            }
            else
            {
            	System.out.print(y+" ");
            	y+=10;
            }
        } 
    }
}

Output:

Enter the value of Nth term 'N' 
9
10 5 60 15 110 25 160 35 210
