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: [33, 66, 9, -63, -67, 30, -47, -2, -26, -91]
Example Output: [49.5, 37.5, -27.0, -65.0, -18.5, -8.5, -24.5, -14.0, -58.5]

Example Input: [27, -78, -59, -24, 69, -13, 27, 48, -2, -82, 23, 13, 19, 7]
Example Output: [-25.5, -68.5, -41.5, 22.5, 28.0, 7.0, 37.5, 23.0, -42.0, -29.5, 18.0, 16.0, 13.0]

Example Input: [-82, 46, -4, -13, -39, -81, -100, -9, 56]
Example Output:
[-18.0, 21.0, -8.5, -26.0, -60.0, -90.5, -54.5, 23.5]
