Tip: Look for the key word, such as the key word in this question is ''Median''
The word Median stands for ''The median is the middle number in a sorted, ascending or descending, list of numbers and can be more descriptive of that data set than the average.''
This means that the number 20 is the correct answer because, They are two numbers behind the number 20 being 0 and 12.5. And there's two numbers in front of the number 20 being 65 and 143.75
