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].

Example Input: [-37, 76, -35, 6, -72, 89, -100, -9, -81, 73, 90, -20]
Example Output: [19.5, 20.5, -14.5, -33.0, 8.5, -5.5, -54.5, -45.0, -4.0, 81.5, 35.0]

Example Input: [43, -22, -75, -92, -34, 33, -60, -65, 89]
Example Output: [10.5, -48.5, -83.5, -63.0, -0.5, -13.5, -62.5, 12.0]

Example Input: [-60, 82, -23, 89, -89, 52]
Example Output:
[11.0, 29.5, 33.0, 0.0, -18.5]
