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: [99, -28, -18, -89, -14, -80, -54, -84, -82]
Example Output: [35.5, -23.0, -53.5, -51.5, -47.0, -67.0, -69.0, -83.0]

Example Input: [-23, 69, -75]
Example Output: [23.0, -3.0]

Example Input: [16, -48, -44, -40, -46, -50, -78, 11, -1, -54, -30, -64]
Example Output:
[-16.0, -46.0, -42.0, -43.0, -48.0, -64.0, -33.5, 5.0, -27.5, -42.0, -47.0]
