A {6, 2, 2, 2, 16, 2} B {37, 37, 3, 3, 3, ?}
The numbers in set A relate to one another through a numerical or abstract pattern. Set B has a similar or a somewhat contrasting pattern .The task in this short but hard puzzle is to identify the logic and complete the incomplete set.
This may be far too simple but:
3?
Reasoning:
6 least prime factor is 2 2 least prime factor is 2 etc... Since list B is all prime, only prime numbers are returned
