They can be: 5 and 2 because 5-2 = 3
3 and 2 are the only prime numbers with a difference of 1.
2 and 3 are the first two prime numbers. The difference between them is 1
5 = 2+3 = 7-2
Any prime numbers greater than 2 will be odd numbers. The difference between two odd numbers will be an even number. So, the difference between two prime (and odd) numbers could be 2, 4, or 6, of the numbers given. The difference could not be 3, 5, or 7.
Twin primes
All prime numbers are odd numbers, except for the number 2. The difference between two odd numbers must be a multiple of 2. So, if the difference between two prime numbers is another prime number, that difference must be 2.Examples:{3, 5}{5, 7}{11, 13}{29, 31}
If you are looking for two prime numbers whose difference is 1, then the numbers have to be 1 & 3.
2-3
It certainly can be! Both the number 2 and 3 are prime numbers. So: 3 - 2 = 1 And there you have it.
Because the definition of twin primes is: two prime numbers with a difference of 2. 3 and 5 are both prime numbers, and their difference is 5 - 3 = 2 → they are twin primes.
All consecutive integers have a difference of one.
As the number 2 is the only even prime number then a difference of 1 occurs only between 2 and 3. All other prime numbers are odd and therefore the minimum difference between successive prime numbers is 2.
