If Circle of Friends keeps growing, it will be harder and harder to find new people to join. When there aren’t enough new recruits to pay all the previous members, the pyramid collapses. In pyramid schemes, only the people at the top make money, but there’s no way to know at what level you joined. Look at how few people there are at the top compared to the bottom. 98% of members end up losing money.

Level 5 has 1,024 members. Which level has 67,108,864 members? (Hint: Start with 1,024 members in level 5 and keep on multiplying by 4 for each level until you get to 67,108,864. Be sure to keep track of the levels. You may want to use a calculator for this one.)
