Hello Johnny - welcome to the forum!
The answer to your question is YES if your iPad supports multi-finger gesturing and if the feature is ON in 'General Settings' - to close an app, simply place 4-5 fingers on the screen w/ your hand open, then quickly bring your fingers together at the center - the app should close and return you to the HOME screen. Also, by swiping right or left w/ 4-5 fingers on the screen, the iPad will switch between your opened apps.
Good luck and let us know if this works for you!
