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].

[-50, 22, -84, -93, 27]
[-14.0, -31.0, -88.5, -33.0]

[-80, -84]
[-82.0]

[45, 59, -51, -78, 88, 23, -67, -85, -44, -7, 35, -57, 13, 92]

[52.0, 4.0, -64.5, 5.0, 55.5, -22.0, -76.0, -64.5, -25.5, 14.0, -11.0, -22.0, 52.5]
