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: [-30, -31, 75, 43, 12, -78, 39, 74, 69, -92, -23, -22]
