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: [-7, 40, 98, 92, -81, 78, -22, 21]
Example Output: [16.5, 69.0, 95.0, 5.5, -1.5, 28.0, -0.5]

Example Input: [-85, 71, 61, 74, -76, -61, 49, -68, -71, -45, -36, -3, 85, -60]
Example Output: [-7.0, 66.0, 67.5, -1.0, -68.5, -6.0, -9.5, -69.5, -58.0, -40.5, -19.5, 41.0, 12.5]

Example Input: [-99, 94, -78, 49, -92, 42, 6, 82, 94, -2, -65]
Example Output:
[-2.5, 8.0, -14.5, -21.5, -25.0, 24.0, 44.0, 88.0, 46.0, -33.5]
