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: [13, -16, 74, -48, 53, 39, -49]
Example Output: [-1.5, 29.0, 13.0, 2.5, 46.0, -5.0]

Example Input: [-61, -4, 59, 97, 77, 15, 50, -66, 99, 90, -77, 53]
Example Output: [-32.5, 27.5, 78.0, 87.0, 46.0, 32.5, -8.0, 16.5, 94.5, 6.5, -12.0]

Example Input: [1, 88, 6, -35, -48, -42, 54, 69, -96, -45, -42, -46, 60, -60, -20]
Example Output:
[44.5, 47.0, -14.5, -41.5, -45.0, 6.0, 61.5, -13.5, -70.5, -43.5, -44.0, 7.0, 0.0, -40.0]
