If you've deleted one or more of your downloaded apps then you should be able to either re-download them for free via the Purchased tab in the App Store app (re-downloading). Or if they are on your computer's iTunes, connect the iPad to your computer and select the iPad on the left-hand side of your computer's iTunes (under 'Devices'), and then use the Apps tab on the right-hand side of iTunes to select and sync them back to the iPad (syncing apps).
