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: [40, 71, -1, -56, -2, 41, 15, -55, -62, 64, 100]
Example Output: [55.5, 35.0, -28.5, -29.0, 19.5, 28.0, -20.0, -58.5, 1.0, 82.0]

Example Input: [-94, 9, 98, -36, 85, 33, -53]
Example Output: [-42.5, 53.5, 31.0, 24.5, 59.0, -10.0]

Example Input: [30, 49, -45, -97, 3, -15, -29, -82, 89, -27, 74, -39, -38]
