By using scanner:-

import java.util.*;

public class Series

{

public static void main(String args[])

{

Scanner sc = new Scanner (System.in);

System.out.print ("Enter a number:");

int n=sc.nextInt();

int j=0;

for( int i=2; i<=n; i++)

{

j= Math.pow(2,i);

System.out.println( j + " , " );

}

}

}
