How do you find a median in a even series of numbers?

if there are 2 medians then take them both and find the average. Like if the numbers are 1,2,3,4,5,6 the medians are 3 and 4 so you would add them both together and divide by how many numbers there are in this case 2; you would get 7 and then divide that by 2 and get 3.5 so that is the median in this case.
