Find the biggest change in values in a list?

Question

How would you find the biggest difference/change in values of a list of numbers in Excel?

An example of what I'm looking for is 1,3,4,5,9,10,11,13

The value I would look for is 4 as this is the biggest difference (between 5 and 9).

Is there a way to do this with a list in Excel?

A picture is worth a thousand words? :p

Description added:

As shown in the image, put the formula in =A2-A1 in Cell B2 and then drag it down. Once you have your values, use the Max formula to get the maximum value as shown in Cell D5
