How can we change the default URL what we get through the view blocks on a basic page?
You can use the Clean Pagination module to get reasonably close:


  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'.


If that doesn't do the trick that module should at least serve as a good starting point to convert the pager to exactly what you're looking for.
