Problem 10 from prior weeks.
Correct!
Explanation:
Solution - if you (add one to all the elements of the series) you'll get a series of all Primes, 5, 7, 13, 19, 31, 43, 61, 73, 103, 109, 139 ......... which are the second elements of the sets of prime twins. Prime twins, are two prime numbers which have a difference of two. Like (5,7) or (17,19) or (101,103) . (149,151) are the next prime twins In which , the second element of the set is 151. Therefore we'll have 151 - 1 = 150. So the next one will be 150.
