A group of tourists, encountering robbers. The robber said: "I have a rule for robbery, the first one pays 100 yuan, the second 150 yuan, the third 200 yuan, and so on!" So tourists rushed to line up to pay money and push each other. The robbers maintained order while collecting money: "Don't cut the queue, whoever cuts in the queue will go last!" The first tourist in line said, "It's good, only lost 100 yuan, and the last one lost 3,000 yuan, haha!"
