The pagination does not match the page numbers displayed. Codeigniter

My controller function

function test($start_from = 0)
{
    $this->load->library('pagination');

    $data = array();

    $per_page = 3;
    $total = $this->activity_model->count_by();

    $config['base_url'] = base_url() . 'test';
    $config['total_rows'] = $total;
    $config['per_page'] = $per_page;
    $config['uri_segment'] = 2;
    $config['num_links'] = 2;
    $config['use_page_numbers'] = TRUE;

    $data['follow'] = $this->activity_model->get($per_page, $start_from);

   $this->pagination->initialize($config); 

   $data['pagination'] = $this->pagination->create_links();

    $this->load->view('front_end/test' ,$data);
}

my route:

 $route['test'] = "user_activity/test";
 $route['test/(:any)'] = "user_activity/test/$1";

model:

 function get($limit,$start_from)
 {
 $sql = "SELECT * FROM user_follow LIMIT $start_from, $limit";

  $query = $this->db->query($sql);
  return $query->result_array();
 }

The problem is that I have pagination 1,2,3,4,5 .... and on each page I show 3 elements. I want to do this in the url to show my page numbers 1,2,3,4,5

When I click the second page, I show 3. When I click the third page of the show 6 url, etc. +3

Is it possible I spend hours searching for tips on the Internet, but nothing, as I understand it [code] $ config ['use_page_numbers'] = TRUE; [/ code] does what I need, but in my case it still doesn't work,

Maybe you can recommend any library?
