Average delta value of a sequence of $N$ $8$-digit numbers

Question

Given a sequence of $N$ $8$-digit numbers, how to calculate the average delta value, thanks.

By "delta value" do you mean the difference between each of the N numbers?
Take the sum of those numbers and divide it by the number of numbers.
That is: add up the delta-values, and divide by how many delta-values you are using; to get the average-delta-value.

Divide the difference between the last element of the sequence and the first by $N-1$.

	Definitely by $N-1$. Edited to correct. – Dan Brumleve Nov 2 '12 at 9:54
	This assumes that the least of the numbers comes first and the greatest comes last, yes? – Cameron Buie Nov 2 '12 at 10:07
	@Cameron, no, I was not assuming any particular order. – Dan Brumleve Nov 2 '12 at 10:11
