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: [-36, -95, 37, 15, -39, 38, 8, -96, 78, 39]
Example Output: [-65.5, -29.0, 26.0, -12.0, -0.5, 23.0, -44.0, -9.0, 58.5]

Example Input: [-2, -57, 85, -7, 81, 57, -60, -87, -18]
Example Output: [-29.5, 14.0, 39.0, 37.0, 69.0, -1.5, -73.5, -52.5]

Example Input: [73, 50, -53, -20, 6, 62, -47, 15]
Example Output:
[61.5, -1.5, -36.5, -7.0, 34.0, 7.5, -16.0]
