It is calculated the same way as if there were an odd number of numbers:
mean = sum of all the numbers ÷ how many numbers there are
The median however is calculated slightly differently. After the numbers have been sorted into order, then:
- If there is an odd number of numbers
eg if there are 15 numbers this is the ((15+1)÷2)th = 8th number.
- If there is an even number of numbers
eg if there are 20 numbers, then the median is the mean of the (20÷2)th = 10th and the (20÷2+1)th = 11th numbers, ie the median is (10th number + 11th number)÷2

The answer to what is the sum of the first positive even numbers is 930. It doesn't mean that you add all the even numbers up until you reach the number 30. In fact, since you have to get the sum of the even numbers, you have to add all even numbers until you get to the number 60.
What is the relation between mean median?
mean = all the numbers added together, divided by the number of numbers median = the middle number - get the numbers in chronological ( smallest 2 biggest) order, then if its odd number of numbers, its the middle one if its even number of numbers, then its the middle two, added together divided by two
