import java.util.Scanner;
public class AverageNOdds {
    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);
        int n;

        System.out.print("Enter value for n: ");
        n = scan.nextInt();

        int count = 0, sum = 0;
        for(int i = 1;count<n;i+=2){
            sum += i;
            count++;
        }

        System.out.println("Sum: "+sum);
    }
}

Output:

Enter value for n: 5
Sum: 25
