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 lowest lowest common factor (lcf) of 12, 6, and 7 is 1.
12 over 7 as a mixed number = 15/7
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
