Which of these prime number pairs qualifies as 'twin primes' because they differ by exactly two?

Answer

11 and 13

Twin primes are defined as pairs of prime numbers separated by exactly two; 11 and 13 fit this pattern, while the other pairs listed have larger gaps.

💡 Did you know?

Twin primes (pairs differing by 2, like 11 and 13) appear to exist infinitely often, yet mathematicians still cannot prove it after 170+ years of trying.
