import java.util.Scanner;
public class KboatSeries
{
public static void main(String args[]) {
Scanner in = new Scanner(System.in);
System.out.print("Enter n: ");
int n = in.nextInt();
double sum = 0;
double denom = 0;
for (int i = 1; i < 2*n; i += 2) {
denom += i + i - 1;
double t = i / denom;
sum += t;
}
System.out.println("Sum = " + sum);
}
}Output
