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: [100, -88, 100, -71, -83, 24, 80, 12, 16]
Example Output: [6.0, 6.0, 14.5, -77.0, -29.5, 52.0, 46.0, 14.0]
