In this task you are given a list of numbers and you need to find the average of each two consecutive values. The average of two numbers a and b is calculated as: (a + b) /2. The output should be a list of the averages of each two consecutive values. A list is presented with two brackets and comma-separated values, like: [1,2,3].

[38, 58, 14, -58, 77, -41]
[48.0, 36.0, -22.0, 9.5, 18.0]

[-26, -40, -22, -65, -61, 16, 26, 51, -24]
[-33.0, -31.0, -43.5, -63.0, -22.5, 21.0, 38.5, 13.5]

[8, -8, 26, -88, 71, -9, -10, -93, -91, -72, -12]

[0.0, 9.0, -31.0, -8.5, 31.0, -9.5, -51.5, -92.0, -81.5, -42.0]
