Good Question: You will need to extend code system/CI_Pagination.php library into application/library/MY_Pagination.php

Math Calculation by @Dan is fine, setup into CI Pagination Library, see below

1) Create file into application/library/MY_Pagination.php more info about Create Library

Overwrite create_links() method from custom method, see below

Revised code section in create_links() method

if ($this->cur_page === $loop){
    // Current page
    $output .= $this->cur_tag_open.($this->cur_page == 1 ? $loop : $loop*($this->per_page)+1).'-'.($loop * $this->per_page).$this->cur_tag_close;
}elseif ($i === $base_page){
 // First page
    $output .= $this->num_tag_open.'<a href="'.$first_url.'"'.$attributes.$this->_attr_rel('start').'>'
               .((($loop)*($this->per_page) - $this->per_page)+1) .'-'. ($loop * $this->per_page).'</a>'
               .$this->num_tag_close;
}else{
     $append = $this->prefix.$i.$this->suffix;
     $output .= $this->num_tag_open.'<a href="'.$base_url.$append.'"'.$attributes.$this->_attr_rel('start').'>'
               .((($loop)*($this->per_page) - $this->per_page)+1) .'-'. ($loop * $this->per_page)
               .'</a>'.$this->num_tag_close;
}

Answer 2

Do some simple math to adjust, so for example if $x = 1

Instead of page 1 being $x page 1 is:

<?php echo $x.'-'.($x * 10); ?>

Page 2 and higher is:

<?php 
    $x++;
    echo (($x)*10)-10)+1.'-'.($x * 10);
?>

Where $x++ counts up for each display.
