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: [-71, 91, 51, -78, -87, -87, 71]
Example Output: [10.0, 71.0, -13.5, -82.5, -87.0, -8.0]

Example Input: [69, -85, -82, 75, -40, 98, -48, 27, -52, -45]
Example Output: [-8.0, -83.5, -3.5, 17.5, 29.0, 25.0, -10.5, -12.5, -48.5]

Example Input: [-5, -22, 93, 68, 29, 62, -33, 71, 45, -58, -73, -14]
Example Output:
[-13.5, 35.5, 80.5, 48.5, 45.5, 14.5, 19.0, 58.0, -6.5, -65.5, -43.5]
