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, -75, 71, -18, -67, -62, 95, 3, 10]
Example Output: [-24.0, -2.0, 26.5, -42.5, -64.5, 16.5, 49.0, 6.5]

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: [29, 77, -61, -32, 68, 48, 15, -28, 4, 6, -73, -12, -55]
Example Output:
[53.0, 8.0, -46.5, 18.0, 58.0, 31.5, -6.5, -12.0, 5.0, -33.5, -42.5, -33.5]
