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.

[2, -13, 2, 44, 20, -16, 94, 63, -97]
[15, 15, 42, 24, 36, 110, 31, 160]

[20, -6, 99, -3, -8]
[26, 105, 102, 5]

[91, -86, -6, 65, -33, -12, 28, 43, -29, -3, 13, -18]

[177, 80, 71, 98, 21, 40, 15, 72, 26, 16, 31]
