There are many ways to use it, such as: "Mom bought a bunch of peaches. I ate half of it on the first day, but I still wanted to eat, so I ate another one. " The next day, I ate half of the remaining peaches and added another one. The third day came again.
Eat half of the remaining peaches and add another one; On the fourth day, eat half of the remaining peaches and add one, just after eating all the peaches. How many peaches did mom buy?
Answer: Because on the fourth day, the peaches left over from the previous day were half eaten and one was added, and just finished eating, leaving 0, so the number of peaches left over on the third day was: (0+ 1)*2=2.
The number of peaches left the next day is (2+ 1)*2=6. The number of peaches left on the first day is (6+ 1)*2* 14.
The number of peaches bought is (14+ 1)*2=30. Mother bought 30 peaches as soon as she bought them.
