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: [67, 45, 59, -50, -28, -70, -84, 69, 72, 53]
Example Output: [56.0, 52.0, 4.5, -39.0, -49.0, -77.0, -7.5, 70.5, 62.5]

Example Input: [74, -35, -92, -40, 97]
Example Output: [19.5, -63.5, -66.0, 28.5]

Example Input: [-1, 75, -1, -37, -38, -10, 70, -75, -98, 39, 37, -15, 60]
Example Output:
[37.0, 37.0, -19.0, -37.5, -24.0, 30.0, -2.5, -86.5, -29.5, 38.0, 11.0, 22.5]
