3, 6, 9, 12, and 13
The range is 11. (14 - 3 = 11)
11, -10, 9
There are nine numbers between 10 and 20: 11, 12, 13, 14, 15, 16, 17, 18, and 19.
16
14 - 10 = 414 + 10 = 24The two numbers are: 14 and 10
The numbers are the first fourteen counting numbers in alphabetical order of their English names. It would not work in any other language, and works only for this set of numbers. That said, the missing numbers are 4 (between 5 and 14) and 9 (between 14 and 1).
14
The range is 11. (14 - 3 = 11)
7, 10, 11, 12, 13, 14, 17
There are 14C5 = 14*13*12*11*10/(5*4*3*2*1) = 2002
How about the integers of : 10 11 12 13 14 15 ..... to infinity
11, 12, 13, 14, 15, 16
11, -10, 9
First 11 composite numbers are 4, 6, 8, 9, 10, 12, 14, 15, 16,18 and 20.
Mean = (12+14+25+10+25+15+11)/7 = 112/7 = 16
The mean (average) of those numbers is 16.
