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: [-63, 4, 4, 49, -83, 99, 85, -18, 11, 83, 73]
Example Output: [-29.5, 4.0, 26.5, -17.0, 8.0, 92.0, 33.5, -3.5, 47.0, 78.0]

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: [92, -79, 17, 91, 49, 10, -50, -35]
Example Output:
[6.5, -31.0, 54.0, 70.0, 29.5, -20.0, -42.5]
