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: [91, 4, -53, 2, 79, -22, -71]
Example Output: [47.5, -24.5, -25.5, 40.5, 28.5, -46.5]

Example Input: [-72, 43, 78, -30, 53]
Example Output: [-14.5, 60.5, 24.0, 11.5]

Example Input: [-68, 30, 56, 87, -78, 33, 59, 52, 65, 22, 63, -26, 82, 12, 33]
Example Output:
[-19.0, 43.0, 71.5, 4.5, -22.5, 46.0, 55.5, 58.5, 43.5, 42.5, 18.5, 28.0, 47.0, 22.5]
