You can do it with forPage() method. Like this:

$posts = $posts->forPage($currentPage, $perPage);

To combine both records you can use merge method with flatten, i,e

$posts = $post_one->flatten(1)->merge($post_two)->sortBy('created_at');

Then you use filter to get the right result:

$filtered = $posts->filter(function ($post, $key) {
    return $key > 2;
});

This skips the first 3 since the key starts from 0...n.

Or you can just slice the collection:

$nextthree = $posts->slice(3, 3);

This skips 3 and takes the next 3 from the collection. You can access the original collections $posts.

At this point the index of the collection is preserved, but to reset it to start from 0...n just use values() method i.e:

$nextthree = $posts->slice(3, 3)->values();
