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: [17, -31, 89, -43, 58, -50, 2, -61]
Example Output: [-7.0, 29.0, 23.0, 7.5, 4.0, -24.0, -29.5]

Example Input: [96, -100, -60, -70, 33, -23, 42, 80, 33, -32, -52, -14, -62, 11]
