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: [57, -26, -99, 61, 13, 31]
Example Output: [15.5, -62.5, -19.0, 37.0, 22.0]

Example Input: [42, -88, 79, -30, 60, 0, -35, -9, -72, 97, -57, -41, -43]
Example Output: [-23.0, -4.5, 24.5, 15.0, 30.0, -17.5, -22.0, -40.5, 12.5, 20.0, -49.0, -42.0]

Example Input: [-32, -16, 97, 31, 98, 99, 98, 12, 32, 60, -94]
Example Output:
[-24.0, 40.5, 64.0, 64.5, 98.5, 98.5, 55.0, 22.0, 46.0, -17.0]
