풀이 :

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 result = a;
            
            for(int j=0; j<n; j++){
                result+= Math.pow(2,j)*b;
                System.out.print(result+" ");
            }
            System.out.println();
        }
        in.close();
    }
}

Math.pow만 알면 어려울것 없는 문제
