Bunuel... Could you please elaborate a bit more

Sent from my Moto G (4) using

GMAT Club Forum mobile appAn evenly spaced set is a set where the distance between all of the numbers is the same.

For instance, this is an evenly spaced set:

2, 4, 6, 8, 10

It's evenly spaced because each number is 2 greater than the previous one. And the median of the set equals the mean of the set (they're both 6).

This is also an evenly spaced set:

4, 10, 16, 22

Again, the median equals the mean (they're both 13.)

Finally, this is an evenly spaced set:

3, 3, 3, 3, 3, 3

It's technically evenly spaced, because the space between each pair of numbers is 0! And sure enough, the median equals the mean.

So,

if you know that a set is evenly spaced, you also know that its median must equal its mean.But what Bunuel mentioned is that it doesn't go the other way. If you know that the median equals the mean of a set, the set

might be evenly spaced. Or it might not.

In other words:
