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].

[-1, 86, 32, 82, -97, 28, -23]
[42.5, 59.0, 57.0, -7.5, -34.5, 2.5]

[52, 88, 91, 51, 48, 72, 93, 44, -23]
[70.0, 89.5, 71.0, 49.5, 60.0, 82.5, 68.5, 10.5]
