#include<math.h>
int main(){
  int n,div,count,num,t;
  scanf("%d",&n);
  printf("%d ",2);
  count=1;
  num=3;
  while(count<n)
  {
    t=sqrt(num);
    div=2;
      while(div<=t)
      {
        if(num%div==0)
          break;
        div++;
      }
    if(div>t)
    {
      printf("%d ",num);
      count++;
    }
    num=num+2;
  }
  return 0;
