Question

What are the twin primes between 1 and 15?

Answer 1

The primes between 1 and 15 are: 2, 3, 5, 7, 11, 13

The value 1 is not prime.

Twin primes are prime numbers separated by 2 units.

In other words, if p and q are prime, and q = p+2, then we consider p,q to be twin primes.

Here's the list of all twin primes between 1 and 15:

3 and 5

5 and 7

11 and 13
