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].

[-24, -20, -8]
[-22.0, -14.0]

[-95, -83, 51, -80]
[-89.0, -16.0, -14.5]

[-9, 87, 36, -68, -14, 93, -7, -38, 98, -45]

[39.0, 61.5, -16.0, -41.0, 39.5, 43.0, -22.5, 30.0, 26.5]
