I'm too tired for math right now, perhaps someone could help me.

Alright, so as you increase in level so the XP you earn from activities increases. I am aware that there is a formula for the XP, and I know what it is, but I'm way too tired to use my brain right now. So my question is: Does the XP gained from activities rise relative to your level. Eg. Level 11 takes 20000 XP to level up. Level 12 takes 25000. Does the XP increase rise to a point where if you continue posting at a constant frequency you will level up in the same interval of time?

Cheers!
