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].

[93, 67, 33, -57, -41, 49, -18, 10, 10]
[80.0, 50.0, -12.0, -49.0, 4.0, 15.5, -4.0, 10.0]

[-49, -91, -7]
[-70.0, -49.0]

[67, -95, -71, 52, -49, 89, 64, -64, -43, -95]

[-14.0, -83.0, -9.5, 1.5, 20.0, 76.5, 0.0, -53.5, -69.0]
