Pagination not chronological on page 2,3,etc.

I have modified my category pages so that they bring in posts in a category in order depending what area of the page.

In my code you can tell im calling an “offset” of 4 in the loop … meaning this section picks up the 4th post in that category and goes from there.

When i click on page 2 of the category, the template is still bringing in the 4th post and so on because i hard-coded it that way.

How can i put in the PHP that if this is page 2 i want it to start with post 8, and if this is page 3 I want it to start with post 12, etc….


<?php
global $more;
$more = 0;

if ( is_front_page () ) $paged = get_query_var( 'page' );
$wp_query = new WP_Query('post_type=post&posts_per_page='.$pagination.'&cat='.$blog_ids.'&paged=' . $paged.'&offset=4');

if ( $wp_query->have_posts() ) : while ( $wp_query->have_posts() ) : $wp_query->the_post();

?>
