1 Full Post then Grid Layout / Gap (missing) Post

Hi

Thanks for creating such a great theme! I’m about to use the theme and testing it local. Will soon go online ??
I’m using the one full post then grid layout. I’m displaying my latest 15 posts. so on the second page there is no Full post. so after 15 latest post one post is “missing”. There is a “Gap”. How can i avoid this gap, so that the page is complete? Can I choose an odd-number of latest post on the frontage, and a even-number of latest post on the following pages?

Thanks a lot for your help!
