I am really sorry for making the careless mistake. I apologise for providing the incorrect answer.
I failed to realised that the mode will change with my original answer.
As such, the maximum value for x is 7 so that the mode doesn't change and the distribution remains valid.
Really sorry.

Oh ya, forgot to mention that x >= 21 is also possible. I have discussed it in the main question chat box a few hours ago.
That's true! Making the unknown (22 or more) sufficiently big to make it both the median and mode.
