A pair of prime numbers that can be expressed in the form E{p, (p + 6)} is deﬁned as a pair of “sexy primes.” A “sexy triplet” is a group of three primes that can be expressed in the form {p, (p + 6), (p + 12)}. All of the following prime numbers are the middle term of a sexy triplet EXCEPT  Choose the correct choice from the following choices.
A) 11  B) 13  C) 17  D) 19  E) 23
definetly a sitter.plug in the values for middle term and calculate.We can see clearly that E for 19 , 19+6 gives 25 which is not a prime   therefore correct answer 19
