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, -27, 100, -100, -52, -57, 25, -14, -46, 81]
Example Output: [-13.0, 36.5, 0.0, -76.0, -54.5, -16.0, 5.5, -30.0, 17.5]

Example Input: [24, 36, -19, 61, 6]
Example Output: [30.0, 8.5, 21.0, 33.5]

Example Input: [-31, 47, -12, 69, 3, 15, 55, 87, 81, 75, -77, -59, -28]
Example Output:
