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: [0, -19, -44, 90, -50, 22, 23, -79, -37, 9, -3]
Example Output: [-9.5, -31.5, 23.0, 20.0, -14.0, 22.5, -28.0, -58.0, -14.0, 3.0]

Example Input: [-47, -92, 82, -29, -21, -46, -47, 55, -27, -9, 39, -94, 81]
Example Output: [-69.5, -5.0, 26.5, -25.0, -33.5, -46.5, 4.0, 14.0, -18.0, 15.0, -27.5, -6.5]

Example Input: [34, -51, 12, 46, -79, -52, 86, 46, -78, 51, 83]
Example Output:
[-8.5, -19.5, 29.0, -16.5, -65.5, 17.0, 66.0, -16.0, -13.5, 67.0]
