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: [-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: [6, 12, 68, 37, 39, 100, -48]
Example Output: [9.0, 40.0, 52.5, 38.0, 69.5, 26.0]

Example Input: [34, -17, -18, -66, 44, 70, -42, 42, -11, -82, -55, -45, 54]
Example Output:
[8.5, -17.5, -42.0, -11.0, 57.0, 14.0, 0.0, 15.5, -46.5, -68.5, -50.0, 4.5]
