In this task you are given a list of integers and you need to find the absolute value of the difference between each two consecutive values. The output should be a list of the absolute value of the differences of each two consecutive values.

Let me give you an example: [7, 1, 5, 8, -4]
The answer to this example can be: [6, 4, 3, 12]
Here is why: The output is a list of the absolute value of the differences of every two consecutive values. So this is a good example.

OK. solve this:
[-84, 65, 38, -26, 36, 54, -27, 46, 54]
Answer:
[149, 27, 64, 62, 18, 81, 73, 8]
