    I am not getting the question., Can anyone please explain what I need to do?

    This is an absolute joke. My code worked on the first try, but the exercise was:

    5% - Demonstrating the ability to write a two-level nested "for" loop in Java.

    95% - Getting your mind back into the mode of undergraduate algebra, and deciphering this ridiciously contrived number series.

    For this website to have any meaningful value at all, that emphasis should really be the reverse.

    Guys, done without creating another object please checkout

    class Solution{
    public static void main(String []argh){
        Scanner in = new Scanner(System.in);
        int t=in.nextInt();
        
        for(int i=0;i<t;i++){
            int a = in.nextInt();
            int b = in.nextInt();
            int n = in.nextInt();
            
            for(int j = 0; j < n; j++){
                a = a + (int)Math.pow(2,j)*b;
                System.out.print(a + " ");
            }
            System.out.println("");
        }
        in.close();

    }
}

    Java solution - passes 100% of test cases

    If using Math.pow(), make sure you cast it to an integer since it returns a double.

    import java.util.Scanner;

class Solution{
    public static void main(String [] args) {
        Scanner scan = new Scanner(System.in);
        int t = scan.nextInt();
        for (int i = 0; i < t; i++) {
            int a = scan.nextInt();
            int b = scan.nextInt();
            int n = scan.nextInt();
            
            for (int j = 0; j < n; j++) {
                a += b * (int) Math.pow(2, j);
                System.out.print(a + " ");
            }
            System.out.println();
        }
        scan.close();
    }
}

    From my HackerRank Java solutions.
