Given a number of terms and a number ‘x’ the task is to calculate the value upto ‘n’ terms of the below given series.
Series: (x-1)/(x+1) + (x-2)/(x+2) + (x-3)/(x+3) + (x-4)/(x+4) + (x-5)/(x+5) …………… + ‘n’ terms.
Note: Value of ‘x’ is to be given by user.
Java
import java.util.*;
public class Series
{
public static void main(String args[])
{
int n=0,x=0;
double result=0.0;
Scanner sc=new Scanner(System.in);
System.out.print("Enter a number: ");
x=sc.nextInt();
System.out.print("Enter number of terms: ");
n=sc.nextInt();
for(int i=1;i<=n;i++)
{
result=result+((double)(x-i)/(x+i));
}
System.out.println("Result of the series: "+result);
}
}
