A leveling system should follow a gradual arc which increases in difficulty as the levels progress. Early levels should be easily achievable to onboard users into the leveling system and as levels increase the gap between them should increase in distance and so difficulty to achieve.

This is an initial recommendation for a leveling system but it should be reviewed and altered if required based on the activity in the community. For example if users are progressing quickly through the levels due to heavy activity then increase the gaps to slow progress.
The points here should take into account the value of any missions you create. For example, if correctly answering a question is worth 400 points, that is ineffective because it completely bypasses levels 1 and 2 so keep the value of missions in mind when creating a leveling system.
