(answer for ur question is if consider a =10 , that line prints a blank space for the value i.e., 10) import java.util.; import java.io.;

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 k =0;
        int r=0;
        int a = in.nextInt();
        int b = in.nextInt();
        int n = in.nextInt();
       // System.out.println(a+" "+b+" "+n );
        for (double j =0;j<n;j++){
        r = r+(int)(Math.pow(2.0,j)*b);
        k=r+a;
        System.out.print(k+" ");
        }
        System.out.print("\n");
    }

    in.close();
}

}
