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: [93, -20, -64, -4, -73, 78, -84, 84, -87]
Example Output: [36.5, -42.0, -34.0, -38.5, 2.5, -3.0, 0.0, -1.5]

Example Input: [-77, -52, 64, 34, -9, 29, -91, 90, 8, -87, 34, 1, -8]
Example Output: [-64.5, 6.0, 49.0, 12.5, 10.0, -31.0, -0.5, 49.0, -39.5, -26.5, 17.5, -3.5]

Example Input: [-33, 0, 53, -83, -37, 2, 97, 19, 11, 34, -50]
Example Output:
[-16.5, 26.5, -15.0, -60.0, -17.5, 49.5, 58.0, 15.0, 22.5, -8.0]
