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].

Input: Consider Input: [-80, -100, -83, -56, -16, 87]

Output: [-90.0, -91.5, -69.5, -36.0, 35.5]


Input: Consider Input: [-12, -20, -43, 3, -38, -4, 34]

Output: [-16.0, -31.5, -20.0, -17.5, -21.0, 15.0]


Input: Consider Input: [22, -68, -79, 21, 46, -81, 28, -49, 99, -99, -67, 86, -10, 54, -46]


Output: [-23.0, -73.5, -29.0, 33.5, -17.5, -26.5, -10.5, 25.0, 0.0, -83.0, 9.5, 38.0, 22.0, 4.0]
