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, -11, -100, 66, 29, 28, 31, -36]
Example Output: [-46.0, -55.5, -17.0, 47.5, 28.5, 29.5, -2.5]

Example Input: [-79, 66, 43, -67, -68, -15, 18, 22, -100, 77, -4, 30, 22]
Example Output: [-6.5, 54.5, -12.0, -67.5, -41.5, 1.5, 20.0, -39.0, -11.5, 36.5, 13.0, 26.0]

Example Input: [-29, 30, -85, 70, 5, -41]
Example Output:
[0.5, -27.5, -7.5, 37.5, -18.0]
