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].

[-99, 61, 95]
[-19.0, 78.0]

[-96, 25, -5, 67, -10, 22, -61, 90, 40, -62]
[-35.5, 10.0, 31.0, 28.5, 6.0, -19.5, 14.5, 65.0, -11.0]
