15,15,15,19,19,22,23,24,27,30,31,35,41,44,45
the mean (average) can be found by adding up all the numbers and dividing that by how many numbers there are.
The mean of this data set is : 405/15 = 27
the mode is the number that appears most often in ur data set
so the mode is : 15
the range is the highest number - the lowest number
the range is (45 - 15) = 30
the median is ur middle number
the median is : 24
ascending order (smallest to largest) is : mode, median, mean, range
Answer:
28.5
Step-by-step explanation:

the difference between 18 and 24 is four, the pattern then carries on...
