How many people are there between the fifth person and 10 person?
(1) enumeration method: the sequence numbers of natural numbers from the 5th to the 10 are: 5, 6, 7, 8, 9, 10. How many people are there between the fifth person and the 10 person? We need to remove the fifth person and the 10 person, so there are 6, 7, 8, 9***4 people.
(2) Formula:10-5-1= 5-1= 4 people.
