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: [-74, -74, 64, -88, 59, 99, 27, -18, -49]
Example Output: [-74.0, -5.0, -12.0, -14.5, 79.0, 63.0, 4.5, -33.5]

Example Input: [42, -88, 79, -30, 60, 0, -35, -9, -72, 97, -57, -41, -43]
Example Output: [-23.0, -4.5, 24.5, 15.0, 30.0, -17.5, -22.0, -40.5, 12.5, 20.0, -49.0, -42.0]

Example Input: [63, 47, 13, 93, -44, -43, 97, -7, 26, 38, -52, 30, 79]
Example Output:
[55.0, 30.0, 53.0, 24.5, -43.5, 27.0, 45.0, 9.5, 32.0, -7.0, -11.0, 54.5]
