Pagination in modx revolution with different page limits for different pages

Question

I was working with getResources and getPages for pagination. Now, I have a requirement that the first page has 6 child Resources and the further pages have 9 child Resources each. I tried manipulating with the limit parameter, but didn't get the results. Is there some way or the other to do the thing using getResources and getPages? Any other method that can be helpful as well.

Thanks in advance.
