Number series program

Number Series #3

(1) + (1+2) + (1+2+3) + (1+2+3+4) + ... + (1+2+3+4+...+n)

Output

Value of n: 5

Sum:35

The program for the series is written in C# programming language and will accept a number as input. The loops will iterate based on the number of entry.

Note: If you are new to C# and Console Application. Try to code First C# Program

Note: Read articles on how to use Loops and Conditions.

Let’s find out a simple and easy way to code these pattern.

Practical Implementation:

using System;

namespace patternProblem.Number

{

    class Number3

    {

        static void Main(string[] args)

        {

            Console.WriteLine("Given series is:");

            Console.WriteLine("(1) + (1+2) + (1+2+3) + (1+2+3+4) + ... + (1+2+3+4+...+n)");

            Console.WriteLine("----------------------------");

            Console.WriteLine();

            Console.WriteLine("Enter value of n: ");

            int n = Convert.ToInt32(Console.ReadLine());

            Console.WriteLine();

            int sum = 0;

            Console.WriteLine("-----Output-----");

            Console.WriteLine();

            for (int i = 1; i <= n; i++)

            {

                for (int j = 1; j <= i; j++)

                {

                    sum = sum + j;

                }               

            }

            Console.WriteLine("Sum of series: " + sum);

            Console.ReadKey();

        }

    }

}

Output:

The input number here is 5. So, the program will iterate five times. The output is shown below:

Given series is:

(1) + (1+2) + (1+2+3) + (1+2+3+4) + ... + (1+2+3+4+...+n)

----------------------------

Enter value of n:

5

-----Output-----

Sum of series: 35
