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.
One example: [7, 1, 5, 8, -4]
Solution is here: [6, 4, 3, 12]
Explanation: The output is a list of the absolute value of the differences of every two consecutive values. So this is a good example.

Now, solve this: [-68, 92, -44, -16, -68, 51, 81]
Solution:
[160, 136, 28, 52, 119, 30]
