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: [-27, 83, -67, 51, -57, -18, -59, 85, -84, 68, 16, 61]
Example Output: [28.0, 8.0, -8.0, -3.0, -37.5, -38.5, 13.0, 0.5, -8.0, 42.0, 38.5]

Example Input: [-68, 93, -7, 31, -45, -70, -28, 78]
Example Output: [12.5, 43.0, 12.0, -7.0, -57.5, -49.0, 25.0]

Example Input: [19, -60, 52, 57, 31, -98, -69, -33, -5, -99, 56, -81, 4]
Example Output:
[-20.5, -4.0, 54.5, 44.0, -33.5, -83.5, -51.0, -19.0, -52.0, -21.5, -12.5, -38.5]
