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: [-25, 29, 0, -66, -92, 11, -89, -35, 80, -69, 81, -69]
Example Output: [2.0, 14.5, -33.0, -79.0, -40.5, -39.0, -62.0, 22.5, 5.5, 6.0, 6.0]

Example Input: [-44, -27, 29, 71, 76, 17, -66, -81]
Example Output: [-35.5, 1.0, 50.0, 73.5, 46.5, -24.5, -73.5]

Example Input: [20, 39, 19, -44, 87, 55, -89, -50, 42, 72, -48, -56, 21, 66, 56]
Example Output:
[29.5, 29.0, -12.5, 21.5, 71.0, -17.0, -69.5, -4.0, 57.0, 12.0, -52.0, -17.5, 43.5, 61.0]
