Add the numbers together, and then - since there are three numbers - divide the result by 3.
27.3 reucuring (33333333333333)
Use the definition of average, write the corresponding equation, and solve it. In this case, the equation is:(3 + x + 16 + 18) / 4 = 11 since there are four numbers.
composite numbers between 11 and 21:12 14 15 16 18
12, 14, 15, 16, and 18 are composite numbers 11, 13, 17, and 19 are prime numbers
12, 14, 15, 16 and 18.
7, 11, (16), 18, 23. The median is 16 (shown in brackets).

Use the definition of average, write the corresponding equation, and solve it. In this case, the equation is:(3 + x + 16 + 18) / 4 = 11 since there are four numbers.
The composite numbers between 11 and 19 are 12, 14, 15, 16 and 18
15.
composite numbers between 11 and 21:12 14 15 16 18
Use the definition of "average". Add the numbers together, then divide the result by 3 (since there are 3 numbers).
lets say these are your numbers 2 4 6 8 10 12 14 16 18 20 add them and you would get 110. Now divide 110 by the amount of numbers you have (10) and your average is 11
12, 14, 15, 16, and 18 are composite numbers 11, 13, 17, and 19 are prime numbers
21 + 17 + 16 = 54 And there are three numbers so average = 54/3 = 18
12, 14, 15, 16 and 18.
They are: 12, 14, 15, 16 and 18
