A list of six numbers is {4, 7, 10, x, 16, 20}. If the median of this list is 12 and the numbers are in ascending order, what is the value of x?

✓ Correct Answer: Option C

For an even number of elements (6), the median is the average of the two middle numbers. The middle numbers are 10 and x. So, (10 + x) / 2 = 12. This means 10 + x = 24, which gives x = 14.
