The first two consecutive prime numbers that have a difference of 20 are the numbers 887 and 907.
The median is the number in the middle of all numbers. There are only 2 numbers. In this case the median is the average of the 2, or 23590625
The first prime above 20 is 23, and then all others (29 is the next).
These are the prime numbers 1-20 2,3,5,7,11,13,17,19
If the only numbers in a set are 20 and 20, the median would be the average of the middle two (20 and 20) which would therefore be 20.

The median is the number in the middle. When you have a even number of numbers, as we do here, we take the mean of the two middle numbers. First put the numbers in ascending order. We have 20 37 49 56 . Since 37 and 49 are the two in the middle we take their mean. 37+49=86 and half of that is 43 so this is the median.
