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: [20, 75, 10, 74, -35, 64, -2]
Example Output: [47.5, 42.5, 42.0, 19.5, 14.5, 31.0]

Example Input: [67, 94, 6, -11, 41, 22, 10, -73, 84]
Example Output: [80.5, 50.0, -2.5, 15.0, 31.5, 16.0, -31.5, 5.5]

Example Input: [-31, -29, -97, 30, -4, 12, 10, 27, 98, 98, 50, 18, -22, -76, 1]
Example Output:
[-30.0, -63.0, -33.5, 13.0, 4.0, 11.0, 18.5, 62.5, 98.0, 74.0, 34.0, -2.0, -49.0, -37.5]
