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].

[6, 81, 44, 22]
[43.5, 62.5, 33.0]

[-88, 35, 91, 54, -25]
[-26.5, 63.0, 72.5, 14.5]

[88, 92, 76, -71, 26, -98, 11, -55, -74, -56, 78, 51]

[90.0, 84.0, 2.5, -22.5, -36.0, -43.5, -22.0, -64.5, -65.0, 11.0, 64.5]
