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: [16, 96, -27, -13, -86, -98, -68, 27, 66, 95, -26, -34, -94]
Example Output: [56.0, 34.5, -20.0, -49.5, -92.0, -83.0, -20.5, 46.5, 80.5, 34.5, -30.0, -64.0]

Example Input: [-61, -4, 59, 97, 77, 15, 50, -66, 99, 90, -77, 53]
