CorrectNot quiteAnswer C
Correct answer: C
Explanation
Letters: P, N, L, J go back 2 each time (16, 14, 12, 10), so the next is 8, which is H.
Numbers: 3, 6, 12, 24 double each time, so the next is 48.
The next term is H48.
Worth noting
H36 adds 12 to 24 as if the numbers rose by a constant. The differences 3, 6, 12 double, so the number doubles.
