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: [98, -73, 94, -63, 27, -13, 26]
Example Output: [12.5, 10.5, 15.5, -18.0, 7.0, 6.5]

Example Input: [-89, -9, -14, -28, 41, 44, 86, 40, 75, 30, -1, 86]
Example Output: [-49.0, -11.5, -21.0, 6.5, 42.5, 65.0, 63.0, 57.5, 52.5, 14.5, 42.5]

Example Input: [16, -53, -30, -11, -69, 14, -94, -23, 91, -94, 1, -97, 44, -29, 69]
Example Output:
[-18.5, -41.5, -20.5, -40.0, -27.5, -40.0, -58.5, 34.0, -1.5, -46.5, -48.0, -26.5, 7.5, 20.0]
