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].

[-29, 30, -85, 70, 5, -41]
[0.5, -27.5, -7.5, 37.5, -18.0]

[-10, 80, -47, 88, 17, 70, -21, 5]
[35.0, 16.5, 20.5, 52.5, 43.5, 24.5, -8.0]

[-89, -57, -18, 98, 22, 54, 30, -23, 84, -48]

[-73.0, -37.5, 40.0, 60.0, 38.0, 42.0, 3.5, 30.5, 18.0]
