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: [-72, 43, 78, -30, 53]
Example Output: [-14.5, 60.5, 24.0, 11.5]

Example Input: [-10, 80, -47, 88, 17, 70, -21, 5]
Example Output: [35.0, 16.5, 20.5, 52.5, 43.5, 24.5, -8.0]

Example Input: [48, 90, -18, -19, 58, 97, -90, 47, 12, 37, -70, -89]
Example Output:
[69.0, 36.0, -18.5, 19.5, 77.5, 3.5, -21.5, 29.5, 24.5, -16.5, -79.5]
