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: [-1, 86, 32, 82, -97, 28, -23]
Example Output: [42.5, 59.0, 57.0, -7.5, -34.5, 2.5]

Example Input: [-100, -17, -69, 0, 35, -39, -34, -70, 21, 55, -74, -63]
Example Output: [-58.5, -43.0, -34.5, 17.5, -2.0, -36.5, -52.0, -24.5, 38.0, -9.5, -68.5]

Example Input: [0, -22, 17, 68, -9, -62, -3, -75, 13, 40, 12, 56, -55]
Example Output:
[-11.0, -2.5, 42.5, 29.5, -35.5, -32.5, -39.0, -31.0, 26.5, 26.0, 34.0, 0.5]
