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]

[-29, 34, -11, 98, 25, -39, -90, -37, 3, -14, -33, 41]
[2.5, 11.5, 43.5, 61.5, -7.0, -64.5, -63.5, -17.0, -5.5, -23.5, 4.0]

[23, 64, -69, 65, -62, 84, -86, 17, -62]

[43.5, -2.5, -2.0, 1.5, 11.0, -1.0, -34.5, -22.5]
