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: [-84, -94, 9, 35, 85, -69, -84, 86, -11, 44]
Example Output: [-89.0, -42.5, 22.0, 60.0, 8.0, -76.5, 1.0, 37.5, 16.5]

Example Input: [-74, -74, 64, -88, 59, 99, 27, -18, -49]
Example Output:
[-74.0, -5.0, -12.0, -14.5, 79.0, 63.0, 4.5, -33.5]
