can not find free apps that i downloaded on my new apple ipad

See this support guide:--> See your purchase history for the App Store or iTunes Store - Apple Support

Please note that the new apps' icons could appear in a different screen page (not in the home screen).

Do you mean you had downloaded apps on a previous iPad and now can't find them on the new one?

Or, You set up the new iPad as new and have downloaded apps and don't see them?
