The title is purely to catch attention. There are just two questions I thought of, quite simple, everyone can just guess. The fastest correct answer gets 100 million, one question, 100 million. Let's begin…\①: 1 35 79 1113 151719 ?\②: 2 6 24 120 ?\③: 8 23 12 27 ?\④: 22 64 230 ?
One evening, villagers fleeing came to a bridge and needed lighting to cross. There was only one flashlight, which could carry at most two people at a time. After crossing, the flashlight couldn't be thrown back, it could only be carried back. The villagers were Brother 1, Brother 2, Brother 5, Brother 7, Brother 8, Brother 10, and Sister 10. Each person's name also indicates their walking speed (in minutes). The crossing speed follows the slower person (for example, if Brother 2 takes Brother 1 across, it takes 2 minutes, and if Brother 1 returns, it counts as 1 minute). How can all villagers get across the bridge in 36 minutes? Friends who can do it faster are welcome to answer.

④: 325 (This problem is quite flexible) Multiply the first number by the sum of the digits of the second number and then add the sum of the digits of the second number.
