Answer 2

Answer:

Two prime numbers are called twin primes if there is present only one composite number between them. Or we can also say two prime numbers whose difference is two are called twin primes. For example, (3,5) are twin primes, since the difference between the two numbers 5 – 3 = 2. The alternative names, given to twin primes are prime twin or prime pair. Also, learn prime numbers here.

Properties of Twin Primes

(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.

5 is an only prime number which is available in two different pairs

Every prime pair other than (3,5) is in the form of (6n-1, 6n+1), where n is any natural number.

The sum of each prime pair apart from (3,5) is divisible by 12.

First Few Pairs of Twin Primes

The first fifteen pairs of twin primes are as follows:

(3, 5), (5, 7), (11, 13), (17, 19), (29, 31), (41, 43), (59, 61), (71, 73), (101, 103), (107, 109), (137, 139), …
