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

x = 12, 14, 16, & 18

Mean = Average of all numbers5 + 14 + 7 + 4 + 12 + 6 + 14 + 6 + 18 + 12 = 9898/10 = 9.8Mean = 9.8

Multiplying fractions is about as easy as it could be.-- The numerator of the product is the product of the two numerators.-- The denominator of the product is the product of the two denominators.(18/16) x (12/14) = (18 x 12)/(16 x 14) = 216/224If you'd like to simplify that answer, it's 27/28 .

There are probably tens of such sets.

Assuming is meant 10 12 14 16 18= total 70there are five numbersso 70 / 5 = 14

4, 6, 8, 9, 10, 12, 14, 15, 16, 18 The average is 11.2

6 + 10 + 14 + 18 = 48/4 = 12 The average of the four numbers is 12.

6 + 10 + 14 + 18 = 48/4 = 12 The average of the four numbers is 12.

The mode is 16.

12, 14, 15, 16, 18 and 20

Based on the sample you have provided, I see that 4 numbers, counting by 2 from 12 to 18, form a repeating sequence. I would expect that the next 4 numbers in this series would again be 12, 14 16, and 18.

(15*12+16*15+18*14)/4913.7142857 is the true average age

The composite numbers between 11 and 19 are 12, 14, 15, 16 and 18
