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: [-17, -67, -20, -30, 91, 51, -35, -90, 6, 93, -32, -97, 98, -11]
Example Output: [-42.0, -43.5, -25.0, 30.5, 71.0, 8.0, -62.5, -42.0, 49.5, 30.5, -64.5, 0.5, 43.5]

Example Input: [-21, 12, 53, 49, 2, -54, -28, 8, -77, 27, -33]
Example Output: [-4.5, 32.5, 51.0, 25.5, -26.0, -41.0, -10.0, -34.5, -25.0, -3.0]

Example Input: [98, 71, -79, 65, 29, -72, -96, 52, 18, 3, -17, -67, -87, -5]
Example Output:
[84.5, -4.0, -7.0, 47.0, -21.5, -84.0, -22.0, 35.0, 10.5, -7.0, -42.0, -77.0, -46.0]
