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: [25, -2, -89, -18, 21, 27, -11, -40, 38, 92, 85, -51, -89, -44, -19]
Example Output: [11.5, -45.5, -53.5, 1.5, 24.0, 8.0, -25.5, -1.0, 65.0, 88.5, 17.0, -70.0, -66.5, -31.5]
