calculating average of difference between numbers using linq

I have a column which has double values. I have to calculate the average of the difference between each values upon all the values in the column.

for example: for 1, 2, 3.5 the average is: ( (2-1) + (3.5-2) ) / 2

Is there a linq way to do it or another smart way?

You can use Zip and Skip together to create the "difference between adjacent numbers" part, and then the normal average:

var differenceAverage = input.Zip(input.Skip(1), (x, y) => y - x).Average();

This relies upon the ability to read input twice (and get the same results each time) however - hopefully that's not a problem in your case.
