Find the median of the set {2, 4, 6, 7, 9, 10}.

1. 5

2. 6

3. 7

4. 8

The correct answer is: 7

The median is the middle value in a set of numbers when they are arranged in order. In this case, the numbers are already in order, so we can easily find the middle value. The middle numbers are 6 and 7, so the median is the average of those two numbers, which is 6.5. Therefore, options A, B, and D are incorrect because they do not accurately represent the median of the set. Option A is the average of the smallest and largest numbers in the set, 2 and 10, which is 6. Option B is just the middle number in the set which is 6, not the median. Option D is the average of the two middle numbers, 6 and 7, which is 6.5, not 8. Hence, option C is the correct answer.
