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: [63, -14, -65, -83, -91, 76, 14, 67, -91, 2, -40]
Example Output: [24.5, -39.5, -74.0, -87.0, -7.5, 45.0, 40.5, -12.0, -44.5, -19.0]

Example Input: [-9, 97, -37]
Example Output: [44.0, 30.0]

Example Input: [-72, -27, 99, -22, -44, 14, 9, -48, -20, 40, -34, -97, -63, -25]
