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: [53, -14, 74, -1, -98, 31, -26, 21, 41, -87, 14, 46]
Example Output: [19.5, 30.0, 36.5, -49.5, -33.5, 2.5, -2.5, 31.0, -23.0, -36.5, 30.0]

Example Input: [77, -69, -47, 13, 70, 22, 70, 22, -29, 80, 83]
Example Output: [4.0, -58.0, -17.0, 41.5, 46.0, 46.0, 46.0, -3.5, 25.5, 81.5]

Example Input: [-73, -84, 98, -71, 33, 96, -31, -5, -94, 52, -91, -74]
Example Output:
[-78.5, 7.0, 13.5, -19.0, 64.5, 32.5, -18.0, -49.5, -21.0, -19.5, -82.5]
