My iPhone is locked and I can't remember the password it only lets me try one password before locking down now it says connect to iTunes?

What am I supposed to do?

Added (1). I have connected to iTunes but it says it needs me to answer on my phone and I can't do that

Connect to itunes

Have you tried doing what it says? Try connecting it to iTunes

Edit: In that case, you'll need to enter DFU mode and restore the device. You can find out how to enter DFU mode here - https://www.theiphonewiki.com/wiki/DFU_Mode

Try connecting to iTunes.
