So the first cast is 75, then it double to 150 on the second, then 300, then 600, and finally to 1200. That's the mana it takes to press R. The total mana cost of using his ultimate n times in a row is 75 if only one cast, 75+150=225 for two, 75+150+300=525 for three, etc. Does this make more sense to you now?
