The midpoint of the data when it is arranged in order.
Step-by-step explanation:
Median can be described as the number that occurs in the middle of a set of numbers that are arranged either in ascending or descending order
For example, the median of the following set of numbers is 5
1, 2, 5, 10, 20
Range is the difference between the highest and lowest values of a set of observations
Range = highest value - lowest value

Answer:

Step-by-step explanation:
This is an arithmetic sequence:

where d is the common difference and n is the index of any given term.
For the given sequence, the common difference is -1:

Knowing both the common difference and the first term, you can write the equation for this sequence:

Then you can use that equation to find the 75th term:

3x-9=0
3x=9
x=3
