How to create Drupal 7 clean pager links?
Hi please check the following link Clean Pagination, Hope this will help you.


  Clean Pagination is a very simple module that allows you to enable clean URL pagination for specified pages. The way Drupal typically works, if you had a view with the URL 'my-view', subsequent pages would normally use a query to pass the page number, as in 'my-view?page=2'. When Clean Pagination is being used for a page, it will create a url like 'my-view/2'.
