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, 80, -33, -48, -65, 9, 53, 34, 54]
[43.0, 23.5, -40.5, -56.5, -28.0, 31.0, 43.5, 44.0]

[-14, 33, -89]
[9.5, -28.0]

[19, 25, -58, -4, -75, 59, 15, -62, 92]

[22.0, -16.5, -31.0, -39.5, -8.0, 37.0, -23.5, 15.0]
