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, 64, -12, -75, 99, 70, -83]
[32.5, 26.0, -43.5, 12.0, 84.5, -6.5]

[83, 67, 5, -15]
[75.0, 36.0, -5.0]

[-23, -7, 82, -27, -60, 47]

[-15.0, 37.5, 27.5, -43.5, -6.5]
