hi guys below is my code i'm not getting the output please correct me

public static void main(String []argh){ Scanner in = new Scanner(System.in);

    int a = in.nextInt();
    int b = in.nextInt();
    int n = in.nextInt();
     int size=n-1;
    int su=a;

    if(a>=0 && b>=0 && n>0){
        for(int i=0;i<=size;i++){
             int power= (int)Math.pow(2,i);
             su=su+power*b;
             System.out.format("%d ",su);
        }
        System.out.println();

    }
    in.close();
}

My solution

import java.util.*;
import java.io.*;
import java.*;

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;
            for(int j=0;j<n;j++)
            {
              sum=sum+(int)(Math.pow(2,j))*b;
              System.out.printf("%d ",sum); 
            }
            System.out.printf("\n");
        }
        in.close();
        
    }
}

My solution, an easy way

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