Circle of Friends
Some friends sat in a circle. Each had a whole number of dollars. The first had $1 more than the second, who had $1 more than the third, and so on. The first gave $1 to the second, who gave $2 to the third, and so on, each giving $1 more than s/he received, as long as possible. There were then 2 neighbours, one of whom had 4 times as much as the other. How many friends were there and how much had the poorest friend at first?
