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 is below.
Q: [7, 1, 5, 8, -4]
A: [6, 4, 3, 12]
Rationale: The output is a list of the absolute value of the differences of every two consecutive values. So this is a good example.
Q: [-4, 3, -44, -34, -91]
A:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
