I cannot sign in to new iPad.

I just received my first Apple device, an 8th generation iPad. Trying to install it's first app, it goes to a screen that says "The Apple ID has not yet been used in the iTunes store. Tap review to sign in, then review your account information." However, when I enter my password to sign in, the prompt goes away for a fraction of a second and comes back. I can enter the password again, and the same thing happens over and over. Can anybody offer any advice?
