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: [67, 94, 6, -11, 41, 22, 10, -73, 84]
Example Output: [80.5, 50.0, -2.5, 15.0, 31.5, 16.0, -31.5, 5.5]

Example Input: [-30, -31, 75, 43, 12, -78, 39, 74, 69, -92, -23, -22]
Example Output: [-30.5, 22.0, 59.0, 27.5, -33.0, -19.5, 56.5, 71.5, -11.5, -57.5, -22.5]

Example Input: [1, -31, 54, 58, -16, 50, 27, -17, -84, 58]
Example Output:
[-15.0, 11.5, 56.0, 21.0, 17.0, 38.5, 5.0, -50.5, -13.0]
