(2,3) are not considered as twin primes, since there is no composite number in between them and the difference between the two primes is not equal to 2.įrom the above we definitions writing the twin primes from 51 to 100,įirst writing all the prime numbers from 51 to 100,įrom the above prime numbers we can say only two twin prime pairs exist, those are (59,61) and (71,73). The alternative names, given to twin primes are prime twin. Or we can also say two prime numbers whose difference is two are called twin primes.įor example, (3,5) are twin primes, since the difference between the two numbers 5 – 3 = 2. Twin prime numbers: Two prime numbers are called twin primes if there is present only one composite number between them. In other words, a twin prime is a prime that has a prime gap of two. A twin prime is a prime number that is either 2 less or 2 more than another prime number. Hint: This type of question to solve we should know the definition of twin prime numbers.
