The median of the 12 primes less than 40 is 15.
The median of the first 7 is the fourth prime = 7.The median of the first 7 is the fourth prime = 7.The median of the first 7 is the fourth prime = 7.The median of the first 7 is the fourth prime = 7.
A median is a form of average. What we usually think of as an average is more correctly know as the mean. It is the total of the numbers divided by the amount of numbers. The median is the middle number in a set of numbers, when they are listed in numerical order. If you had a list of numbers and one of these was much higher than all the rest, then the mean might not really represent a true reflection of the average as we think of it. Say your numbers were 11, 15, 30, 1200, 4, 19 and 10. Getting the average of those is going to give 184.1429 which isn't really a good representation. The 1200 is causing that value to be considerably higher than most of the numbers. In this case using the median is better. Listing the numbers in order and finding the middle one gives us 15. The median will therefore be 15, which looks more realistic. See the related questions below for more information.
The median for the first 20 prime numbers would be 30. This is because the middle two numbers of the first 20 prime numbers are 29 and 31. To find the median from this, we need to find the average of these two numbers. This is 30.

The first 8 prime numbers are: 2 3 5 7 11 13 17 and 19 The median is: (7+11)/2 = 9
The median of the 12 primes less than 40 is 15.
The median of the first 7 is the fourth prime = 7.The median of the first 7 is the fourth prime = 7.The median of the first 7 is the fourth prime = 7.The median of the first 7 is the fourth prime = 7.
The numbers 1103, 1109, 1117, 1123, 1129, 1151, 1153, 1163, 1171, 1181, 1187 and 1193 are prime.
The prime factors of 1200 are 2, 3 and 5.
The prime factorization of 1200 is 2 x 2 x 2 x 2 x 3 x 5 x 5 or 24 x 3 x 52.

When the median has two numbers, you add the two together and divide by 2 . The median doesn't really have 'two numbers'; you are talking about finding the median of a set of numbers that contains an even number of numbers. The median is half-way between the two.
