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, 17, -25, -21, 45, 34, -39, 21, 71]
Example Output: [-9.5, -4.0, -23.0, 12.0, 39.5, -2.5, -9.0, 46.0]

Example Input: [-80, 99, -49, -90, 63, 15, 39, -5, -17]
Example Output: [9.5, 25.0, -69.5, -13.5, 39.0, 27.0, 17.0, -11.0]

Example Input: [-43, 34, 75, 4, 7, 100, 79, -19, -96, 80, 95, 84, 47, -6]
