What is a twin prime pair?

Answer 1

A twin prime pair are two primes separated by 2. For example, 3 and 5 are twin primes.

It is conjectured that there are an infinite number of twin primes.

Answer 2

A twin prime is a prime number that is either 2 less or 2 more than another prime number-for example, the twin prime pair (41, 43). In other words, a twin prime is a prime that has a prime gap of two.
