t is No. queries and n is power of 2. With t we can execute the nested For-loop. As shown below..............

    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("");
    }
