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: [29, 38, -89, -84, 82, -45, -18, 49, -59, 14, 90, -52, -60, 16, -29]
Example Output: [33.5, -25.5, -86.5, -1.0, 18.5, -31.5, 15.5, -5.0, -22.5, 52.0, 19.0, -56.0, -22.0, -6.5]

Example Input: [-19, 17, -76, 38, 49, -1, 98, -89, -27, 49, 6, 44, 81, 0, 80]
Example Output: [-1.0, -29.5, -19.0, 43.5, 24.0, 48.5, 4.5, -58.0, 11.0, 27.5, 25.0, 62.5, 40.5, 40.0]

Example Input: [-70, -83, 83, 33, 55, 97, -53, -10, 15]
Example Output:
[-76.5, 0.0, 58.0, 44.0, 76.0, 22.0, -31.5, 2.5]
