The missing term is 7p + 2.

If p = 3 (the minimum possible value of p), then 6p = 18, which is between 15 and 95.
So, 7p + 2 = 7 * 3 + 1 = 22, none of the answer choice.
The maximum possible value of p = 13 (as 6 * 17 = 102, out of range) then 6p = 6 * 13 = 78. So, 7p + 2 = 7 * 13 + 2 = 93, none of the answer choice.
Try other possible prime numbers less than 13. If p = 11, then 7p + 2 = 79, which is option B.

The correct answer is B.
