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: [-42, 38, 39, -43, -66, -57, -9, 47, -25, -24, -89]
Example Output: [-2.0, 38.5, -2.0, -54.5, -61.5, -33.0, 19.0, 11.0, -24.5, -56.5]

Example Input: [-37, 76, -35, 6, -72, 89, -100, -9, -81, 73, 90, -20]
