Question

how to Write A Program TO PRINT THE SUM OF THE FOLLOWING SERIES
S=(1+2)/(1*2)+(1+2+3)/(1*2*3)+ - - - - - - UPTO N TERMS in java using bluej.

Answer 1

Answer:

This is the required program for the question in Java.

import java.util.*;

public class Sum  {

   public static void main(String args[])   {

       int n,i;

       float s=0.0f,p=1.0f,q=1.0f;

       Scanner sc=new Scanner(System.in);

       System.out.print("Enter limit - ");

       n=sc.nextInt();

       sc.close();

       for(i=2;i<=n+1;i++) {

           q+=i;

           p*=i;

           s+=q/p;

       }

       System.out.println("Sum is: "+s);

   }

}

Note: Here, p calculates the values of denominator part and q calculates the value of numerator part of each term in the series. Then, the value of q/p is added to the sum variable. The sum is displayed on the screen after calculation.
