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: [-25, 38, 7, 52, -63, -81, -63, -74, 85, 27, 2]
Example Output: [6.5, 22.5, 29.5, -5.5, -72.0, -72.0, -68.5, 5.5, 56.0, 14.5]

Example Input: [-68, -9, -91, -69, -63, -48, -52, -57, -56, -85, 75, -19]
Example Output: [-38.5, -50.0, -80.0, -66.0, -55.5, -50.0, -54.5, -56.5, -70.5, -5.0, 28.0]

Example Input: [40, -40, 40, 28, -62, 35, -83, -99, -67, 62, -87]
Example Output:
[0.0, 0.0, 34.0, -17.0, -13.5, -24.0, -91.0, -83.0, -2.5, -12.5]
