Answer:
the answer would be 28
Explanation:
first lets order them from greatest to least:
42, 40, 40, 40, 39, 38, 38, 37, 37, 28
now that we have these we can see that the biggest jump in difference is between 37 and 28 which is 9 numbers away from each other, every other number is filled with gaps of 2 or 1 so 9 is definitely a big jump. that is the outlier
