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: [-29, -56, -77, -51, 5, -12, -80]
Example Output: [-42.5, -66.5, -64.0, -23.0, -3.5, -46.0]

Example Input: [-26, -40, -22, -65, -61, 16, 26, 51, -24]
Example Output: [-33.0, -31.0, -43.5, -63.0, -22.5, 21.0, 38.5, 13.5]

Example Input: [5, 98, 1, -77, -11, -79, -59, -15, -14]
Example Output:
[51.5, 49.5, -38.0, -44.0, -45.0, -69.0, -37.0, -14.5]
