Increase the size of pagination text

When I break a post up into mulitple pages, the pagination font is very small. I’m trying to make the pagination (page numbers) at the bottom of the post larger because some of my readers are missing the rest of the post because they don’t see the “page 1 2”.

I want to make that twice the current size. Please help

Here’s an example
