Answer:
MEDIAN :
At first, you need to find the prime numbers. By this, you do need to know what is prime numbers. I got an explanation for a prime number form Wiki: a prime number or (a prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself. A natural number greater that 1 that is not a prime number is called a composite number. For example, 2 is a prime because 1 and 2 are its only positive integer factors., whereas 4 is composite because it has the divisors 2 in addition to 1 and 4.
As such, you could get the first five prime numbers in natural numbers: {2,3, 5, 7, 11}
Next, you do also need to know what is a mean for a ranked set. In statistics and probability theory, the median is the numerical value separating the higher half of a data sample, a population, or a probability distribution, from the lowest half. For example, the median of {3, 3, 5, 9, 11} is 5. And if there is an even number of observation, then there is no single middle value; the number is then usually defined to be the mean of the two middle values. Like: the median of {3, 5, 7, 9} is (5 + 7) / 2 = 6)
MEAN :
First 5 prime numbers =2,3,5,7,9
Mean= 5
2+3+5+7+9 = 5
26
=5.2.
