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: [20, -40, -63, 94, -53, -6, 18, 47, -18, -20, -94, 71, 17, 26]
