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: [-7, 40, 98, 92, -81, 78, -22, 21]
Example Output: [16.5, 69.0, 95.0, 5.5, -1.5, 28.0, -0.5]

Example Input: [67, -95, -71, 52, -49, 89, 64, -64, -43, -95]
Example Output: [-14.0, -83.0, -9.5, 1.5, 20.0, 76.5, 0.0, -53.5, -69.0]

Example Input: [-34, -41, -80, -25, -77, -50, -70, 36, 51, 53, 0, 83, -100, 56]
Example Output:
[-37.5, -60.5, -52.5, -51.0, -63.5, -60.0, -17.0, 43.5, 52.0, 26.5, 41.5, -8.5, -22.0]
