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: [93, -20, -64, -4, -73, 78, -84, 84, -87]

Output: [36.5, -42.0, -34.0, -38.5, 2.5, -3.0, 0.0, -1.5]


Input: Consider Input: [6, -20, 92, 43, -89, 46, 1, -64, -71, 88]

Output: [-7.0, 36.0, 67.5, -23.0, -21.5, 23.5, -31.5, -67.5, 8.5]


Input: Consider Input: [80, 29, 7, 76, -45, -34, -34, 20, 75, -52, -30, -20]
