Hey,
You need to check with
https://support.google.com/adsense/answer/6090783?hl=en to see if you are missing something simple. The page views on Google Analytics will always show 10-20% more than your Adsense views. If the percentage is higher than 20%, you need to do a thorough check of your website. When talking to advertisers, its better to tell your Analytics views, because they will automatically discount a good percentage of your views.
Hope this helps.
