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].

[40, -94, 40, -52, -80]
[-27.0, -27.0, -6.0, -66.0]

[6, 14, 78, 45, -59, -79, -72, 35, 72, 100, -7, -76, -75]
