Question

write a java program to display the series 1/2+3/4+5/6+7/8​

Answer 1

Required Answer:-

Question:

• WAP in Java to display the sum of the series - 1/2 + 3/4 + 5/6 +...

Solution:

Here comes the program.

import java.util.*;

public class Sum {

 public static void main(String[] args) {

     int n, i;

     double s=0.0, a=1.0, b=2.0;

     Scanner sc=new Scanner(System.in);

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

     n=sc.nextInt();

     for(i=1;i<=n;i++,a+=2,b+=2)

        s+=a/b;

     System.out.println("Sum: "+s);

     sc.close();

 }

}

Algorithm:

1. START.
2. Ask the user to enter the limit, say n.
3. Assume a=1, b=2,s=0.
4. Iterate a loop n times.
5. Add the value of a/b to s.
6. Increment the value of a and b by 2.
7. Display the value of s after termination of loop.
8. STOP.
