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].

[-43, 46, 22, -76, 46, -87, -59]
[1.5, 34.0, -27.0, -15.0, -20.5, -73.0]

[28, -83, -37, -51]
[-27.5, -60.0, -44.0]

[-31, -1, 55, -54, 33, -7, -44, -3, 76, -76, 71, -61, 61]
