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.

[67, 94, -77, 4, 67, 88]
[27, 171, 81, 63, 21]

[-76, -34, -42, -67, 18, -71, -11, 36, 61, 98, 37, 25, 96, 2]
[42, 8, 25, 85, 89, 60, 47, 25, 37, 61, 12, 71, 94]

[-4, 67, -44, -74, -70]

[71, 111, 30, 4]
