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]

[56, -80, -51, -27, -97, 98, 99, -25, -55, 99, -9, -66, -83, 38, -95]
[-12.0, -65.5, -39.0, -62.0, 0.5, 98.5, 37.0, -40.0, 22.0, 45.0, -37.5, -74.5, -22.5, -28.5]

[58, -16, -79, 52, 75, 94, 22, 54, 86, -68]

[21.0, -47.5, -13.5, 63.5, 84.5, 58.0, 38.0, 70.0, 9.0]
