Blog Pagination URL: Remove “P” from url and get correct page number

I want my URLs to be like the following: domain.com/blog/2

Currently they are: domain.com/blog/P6

RIght now if I show 6 articles per page, my pagination will jump by 6.

For instance, Page 1 will be /, page 2 will be /P6/, page 3 will be /P9/, ect.
