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: [87, 34, 59, -97, -67, -71, -28, -51, 56]
Example Output: [60.5, 46.5, -19.0, -82.0, -69.0, -49.5, -39.5, 2.5]

Example Input: [-29, -99, 93, 44, 8, -55, 48, 2, 22, 45]
Example Output: [-64.0, -3.0, 68.5, 26.0, -23.5, -3.5, 25.0, 12.0, 33.5]

Example Input: [41, -58, 72, -59, 27, 68, 55, 59, -33, -33, -6, -30, -88]
Example Output:
[-8.5, 7.0, 6.5, -16.0, 47.5, 61.5, 57.0, 13.0, -33.0, -19.5, -18.0, -59.0]
