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: [-13, 97, -60, -24, 6, 8, -89, -98, 20, -76]
Example Output: [42.0, 18.5, -42.0, -9.0, 7.0, -40.5, -93.5, -39.0, -28.0]

Example Input: [68, -24, 24]
Example Output: [22.0, 0.0]

Example Input: [-70, -20, -16, -96, -15, -39, -44, 23, 86, -72, 40, 55, -88, -95, 77]
