What does mean by question Mark on the next rating number?
It means provisional rating and the player has not played enough games to have a solid rating.

The question mark means the rating is provisional. Reasons include:
The player has not yet finished enough rated games against opponents of similar strength in the rating category.
The player hasn't played enough recent games. Depending on the number of games you've played, it might take around a year of inactivity for your rating to become provisional again.
Concretely, it means that the Glicko-2 deviation is greater than 110. The deviation is the level of confidence the system has in the rating. The lower the deviation, the more stable a rating is.
