1. 190
2. 190+190x0.25=190+50=240
3. 190+240x0.25=250
4. 190+250x0.25=252
5. 190+252x0.25=253

The growth would stop at around 250 members.
I like to discuss with you, you seem to have a clue.
I did it differently. You're not counting new joins in the rebills and 25% through multiple months (those members that stay for 3+ months...) etc. But anyway, possible i messed up somewhere. Plus, i based that on the current member volume, i dont know how you got there.
