Question

What are twin prime numbers?​

Answer 1

twin prime conjecture

…that there are infinitely many twin primes, or pairs of primes that differ by 2. For example, 3 and 5, 5 and 7, 11 and 13, and 17 and 19 are twin primes. As numbers get larger, primes become less frequent and twin primes rarer still.

Answer 2

$\huge { \underline{ \underline{ \mathsf{ \pink{Required \ Answer :-}}}}}$

Twin prime numbers are those numbers who have a composite number between them.

$\sf\underline{Alter}$

Or we can they are the numbers which have a difference of two numbers between them.

For e.g :-

( 11 , 13 )

( 5 , 7 )

( 17 , 19 )

( 41 , 43 )
