What is essential here is to notice that k is defined as a sum of two numbers so that in order to compute its prime factors, we must first find k.
Thus k = 247, then its prime factors are 17 and 19, whose mean is 17+19/2 = 16
Answer C
Thus k = 247, then its prime factors are 17 and 19, whose mean is 17+19/2 = 16
