Getting page start number

[runnerjp]

Ok guys i have a page where im echoing a count number in a loop...

$counter2= '1';

$counter2++;

 

How can i make it so on ach page of the pagination it adds 5 to the previous value??

 

so on each page it will start with these numbers.

page1  =  2, page 2  =  7 , page3  =  12, page4  =  17, page5  =  22, page6  =  27

 

To get the page number i use this

 

$pagenum                    =(is_numeric($pagenum) && $pagenum >= 1) ? (int)$pagenum : 1;
