Two prime numbers p and q are said to be twin if q=p+2.

Twin prime numbers are numbers whose difference is 2, because they are the nearest together that any primes can be, with the exception of 2 and 3. Except for the Prime number 2, all prime numbers must be odd, so when two consecutive odd numbers are prime, they are called twin primes. There might be an infinite number of twin primes; that has not yet been proven. There are an infinite number of prime numbers.

There is only one example of triplet primes: 3, 5, 7.

Here are examples of twin primes:

3, 5

5, 7

11, 13

17, 19

29, 31

41, 43

59, 61

71, 73

101, 103

107, 109

137, 139

149, 151

179, 181

191, 193

197, 199

227, 229

239, 241

281, 283

311, 313

347, 349
