What is the median of the following numbers: 7, 9, 12, 15, 18, 20?
  • Step 1: Write down the numbers in order: 7, 9, 12, 15, 18, 20.
  • Step 2: Count how many numbers there are. There are 6 numbers.
  • Step 3: Since there is an even number of values (6), the median will be the average of the two middle numbers.
  • Step 4: Identify the two middle numbers. The middle numbers are the 3rd and 4th numbers: 12 and 15.
  • Step 5: Add the two middle numbers together: 12 + 15 = 27.
