This is my Solution:

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 a = in.nextInt();
            int b = in.nextInt();
            int n = in.nextInt();
            int sum=a+b;
            for(int j=1;j<=n;j++){
                System.out.print(sum+" ");
                sum=(int)(sum+(Math.pow(2, j)*b));  
            }
            System.out.println();
        }
        in.close();
    }
}

This is my solution

    for(int i=0;i<t;i++){
        int a = in.nextInt();
        int b = in.nextInt();
        int n = in.nextInt();
        int n_count = 0 ;
        int b_sum = 0;
        while(n_count <= n-1){
            b_sum += (int) Math.pow(2,n_count)*b;
            int result = a + b_sum;
            System.out.print(result + " ");
            n_count++;
        }
        System.out.println();
    }

class Solution{ public static void main(String []argh){ Scanner in = new Scanner(System.in); int t=in.nextInt(); for(int i=0;i

        for(int j=1;j<=n;j++){
            double k = Math.pow(2, j);
            int rounded = (int) Math.round(k);
            int result = a + (b * (rounded - 1));
            System.out.print(result + " ");

        }
        System.out.print("\n");

    }

    in.close();
}

}
