What's the average CPM for mobile ads in United States(banners, native, interstital)?

Hello everyone,

I would like to know an recently (2017) average CPM for mobile ads (Banners, Native and Interstitial) in United States for Ad Networks like AdMob, Mopub, Facebook Audience Network and Fyber.

Do you guys have any idea, because all the info that I could find is from 2-3 years ago.
