Long Answer:
First Step: Make it into numerical order, least to greatest:
32, 35, 38, 40, 42, 46, 48, 48, 50, 51, 52, 53, 54, 56
Second Step: Mark off every number on each side one by one and try to get to the middle.
Third Step: If you get to the middle and there are two numbers, add them and divide by 2, so 48 + 48 = 96, 96 / 2 = 48, which is still the same because the middle have both of the same numbers.
Short Answer: 48
