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: [30, 4, 19, 28, -28, 81, 78, -64, -4, 6, -33, 44, -76]
Example Output: [17.0, 11.5, 23.5, 0.0, 26.5, 79.5, 7.0, -34.0, 1.0, -13.5, 5.5, -16.0]

Example Input: [-12, -20, -43, 3, -38, -4, 34]
Example Output: [-16.0, -31.5, -20.0, -17.5, -21.0, 15.0]

Example Input: [54, -34, 99, -59, 35, 16, 1, 26, -55, 91, 70, -85, -54, -64, -27]
Example Output:
[10.0, 32.5, 20.0, -12.0, 25.5, 8.5, 13.5, -14.5, 18.0, 80.5, -7.5, -69.5, -59.0, -45.5]
