You can select 9 numbers for the first digit, 8 numbers for the second digit, and 7numbers for the third digit; so 504 (e.g. 9*8*7) different three digit numbers can be written using the digits 1 through 9.
9, 90 and 900
9
If the numbers can be repeated and the numbers are 0-9 then there are 1000 different combinations.
You can find the mean by adding the numbers and dividing that number by how many numbers their is. For example 2 plus 5 plus 2 equals 9 and because there is the three numbers 2 5 and 9 you divide 9 by 3 and get 3 as an answer. This an a example as to how you find the mean.
27 = 3*936 = 4*945 = 5*927, 36, and 45 are three different numbers whose greatest common factor is 9.

It means write down three pairs of numbers that are relatively prime like 4 and 9, 5 and 6, 13 and 25
Three and six you numbskull.

The numbers are 8, 9 and 10.
1, 25 and 1024 are three examples.
