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: [-81, -5, -18, -96, 28, -86, 50, 63, 80, -52]
Example Output: [-43.0, -11.5, -57.0, -34.0, -29.0, -18.0, 56.5, 71.5, 14.0]
