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].

Example Input: [93, 23, -18, 1, -66]
Example Output: [58.0, 2.5, -8.5, -32.5]

Example Input: [0, -85, 1, 64, 53, -80, 18, 45, 57, -84, -11, 80, -23, 91]
