What do you do if there is 2 median?

In a odd set of numbers the middle number is the median, but if there's a even set of numbers, say 6 for example, you add the two numbers in the middle then divide them by 2 and you will end up with the middle of the two middle numbers- what a mouthful! Or another way to do it is if the two middle numbers are say 4 and 6 then obviously the number between them is 5

Example: Find the median for these numbers.

2,3,4,5,6,7

4+5=9

9 divided by 2=4.5

Therefore the answer is 4.5
