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: [56, -71, -75, 36, 77, -13, 72, 40, -43]
Example Output: [-7.5, -73.0, -19.5, 56.5, 32.0, 29.5, 56.0, -1.5]
