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].

[-72, 43, 78, -30, 53]
[-14.5, 60.5, 24.0, 11.5]

[-29, -56, -77, -51, 5, -12, -80]
[-42.5, -66.5, -64.0, -23.0, -3.5, -46.0]

[45, 48, -28, 45]

[46.5, 10.0, 8.5]
