Answer:
7
Step-by-step explanation:
The mean is the average of the numbers. Add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
7 + 14 + 7 + 16 + 16 = 60
60 / 5 = 12

In a proportion there are letters assigned to represent various numbers. a, b, c, and d.
a, b, c, and d are 4 non-zero rational numbers that are terms of proportion.
a/b = c/d or a:b = c:d
a and d are the end terms or known as the extremes.
b and c are the middle terms or known as the means.
With this information, we can gather that the extremes of the following proportion are 3 and 60.
3/15 = 12/60 ; a/b = c/d
a = 3 ; b = 15 ; c = 12 ; d = 60
3 and 60 are the extremes
15 and 12 are the means
