No, 21 and 23 are not twin prime numbers. Twin primes are pairs of prime numbers that differ by 2, such as 3 and 5, or 11 and 13.
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.
twin primes are 2 prime numbers with a difference of 2 the prime numbers 5 and 3 are twin primes because 5 minus 3 equals 2 so 109 and 111 are not twin primes
Prime numbers that differ from each other by exactly 2 are twin primes. Examples of twin primes are 3 and 5, 17 and 19, 599 and 601.

The numbers 11 and 13 are prime twins. Prime twins are consecutive prime numbers that differ by a difference of two. For example, 3 and 5, 7 and 9 are twin primes.

Perhaps you mean twin primes? In which case the answer is no: 111 is divisible by 3 so is not prime.
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).
A twin prime is a prime number that differs from another prime number by two. Except for the pair (2, 3), this is the smallest possible difference between two primes. Some examples of twin prime pairs are (3, 5), (5, 7), (11, 13), (17, 19), (29, 31) and (41, 43). Sometimes the term twin prime is used for a pair of twin primes; an alternative name for this is prime twin. Hope this helps :)
