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: [-99, 100, -53, -61, 64, -96, 13]
Example Output: [0.5, 23.5, -57.0, 1.5, -16.0, -41.5]

Example Input: [48, 69, 7, 42, 46, -27, -58, 24, 95, 57]
Example Output: [58.5, 38.0, 24.5, 44.0, 9.5, -42.5, -17.0, 59.5, 76.0]

Example Input: [-90, -35, -46, 26, 52, -68, -11, -27, -20, 22]
Example Output:
[-62.5, -40.5, -10.0, 39.0, -8.0, -39.5, -19.0, -23.5, 1.0]
