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].

[-12, -20, -43, 3, -38, -4, 34]
[-16.0, -31.5, -20.0, -17.5, -21.0, 15.0]

[51, -95, 3, 67, 33, -55, -29, 65, -85, -91]
[-22.0, -46.0, 35.0, 50.0, -11.0, -42.0, 18.0, -10.0, -88.0]

[18, -22, -48, 77, 77, -4, -60, 77, 55, -31, 9, 92, 1]

[-2.0, -35.0, 14.5, 77.0, 36.5, -32.0, 8.5, 66.0, 12.0, -11.0, 50.5, 46.5]
