Because no one should have to say, "I was never any good at math."
The pairs of answers are not included in your question. However, the current mean is 16 4/9. Any two numbers with a mean higher than that would produce a higher mean.
So, find the average (mean) of each pair of numbers. The one greater than 16 4/9 is your answer. Also, I would suspect that only one answer works, so the one with the highest mean will probably be the only correct answer.
