well, the mode is basically asking you what number appears the most frequently.
6, 6, 7, 8, 9, 9, 9, 12, 12, 12, 15
in the sequence, the mode would either be 9 or 12 because those are the numbers that appear the most frequently.
1, 3, 5, 151, 2, 3, 6, 7, 14, 21, 421, 3, 5, 151, 2, 3, 6, 7, 14, 21, 42
7/15
3/5, 9/15, 12/20, 3n/5n for all n = 5, 6, 7, ...
The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. Factors are numbers that can be multiplied together to give the original number.
The lowest lowest common factor (lcf) of 12, 6, and 7 is 1.
mode
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
The mode is 15 because it occurs most often
One possibility: 5, 6, 7, 7, 7, 12, 12, 13, 14, 15, 16, 18
Mean = 6 Mode = 5.
The five numbers are divided by that 5 when added 7 + 8 + 12 + 15 + 18 = 60 60/5 = 12
-12 + 6 - 10 - 6 +15 = -7
6.
8 + 7 - 9 + 6 - 3 = 9 8 + 7 = 15 15 - 9 = 6 6+6 = 12 12 - 3 = 9
252.
Mean = 7.9 Median = 7 and 8 Mode = 4 and 12 Range = 2 to 15.
Mean = 13.44.. recurring Median = 15 Mode = 9 and 15 Range = 17
