Range = Maximum - Minimum = 20 - 8 = 12.
There are probably tens of such sets. Some are: 5, 6, 7, 7, 8, 11, 13, 14, 15, 16, 17, 18 5, 6, 7, 7, 7, 12, 12, 14, 15, 16, 17, 18 5, 6, 7, 7, 7, 12, 12, 14, 14, 16, 17, 18 5, 6, 7, 7, 7, 12, 12, 14, 14, 15, 17, 18 5, 6, 7, 7, 7, 12, 12, 14, 15, 15, 17, 18 5, 6, 7, 7, 7, 12, 12, 14, 15, 16, 16, 18 5, 6, 7, 7, 7, 12, 12, 14, 14, 16, 16, 18
They are: 8+9+10+12+14+15+16+18 = 102
True, but the LCM of 8, 14 and 18 is 504.
The range is 12 and the standard deviation is 3.822448314.
8, 8, 8, 10, 14, 15 The mean is 10.5 The median is 9. The mode is 8. The range is 7.
Range = Maximum - minimum = 18 - 0 = 18
Range = Maximum - Minimum = 20 - 8 = 12.
11
4, 6, 8, 9, 10, 12, 14, 15, 16, 18, and 20 are composite. The other numbers in that range are prime.
There are probably tens of such sets. Some are: 5, 6, 7, 7, 8, 11, 13, 14, 15, 16, 17, 18 5, 6, 7, 7, 7, 12, 12, 14, 15, 16, 17, 18 5, 6, 7, 7, 7, 12, 12, 14, 14, 16, 17, 18 5, 6, 7, 7, 7, 12, 12, 14, 14, 15, 17, 18 5, 6, 7, 7, 7, 12, 12, 14, 15, 15, 17, 18 5, 6, 7, 7, 7, 12, 12, 14, 15, 16, 16, 18 5, 6, 7, 7, 7, 12, 12, 14, 14, 16, 16, 18
8 and 14/15
They are: 8+9+10+12+14+15+16+18 = 102
True, but the LCM of 8, 14 and 18 is 504.
LCM(14, 8, 18) = 504.
The first 10 composites are: 4, 6, 8, 9, 10, 12, 14, 15, 16, 18.
