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].

Input: Consider Input: [20, 57, 16, -66, -30, -89, 64, -22, 7, -36, -19, -71]
