Whats the outlier (i tried every calculator and it said there are none!)

42,8,54,37,29

The outlier would be 8 (There are no calculations needed). and the reason why it would be 8 is because the rest of the bigger numbers seem to fit on a number line and then you have 8 that seems like a weird number that doesn't belong with the rest of the other numbers (basically its the number that stands out to be weird or out of the ordinary)

An outlier is a number value that is much larger or smaller than the others. In this case, the lowest number there is is 8. This means 8 is the outlier.
