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: [1, 77, 55, -37, -65, 80, 31, -37, -61, 3, -80]
Example Output: [39.0, 66.0, 9.0, -51.0, 7.5, 55.5, -3.0, -49.0, -29.0, -38.5]

Example Input: [-100, 79, -67, -4, 80, 46, -45, -82, 89, 51, 34, 23, -73, 53]
Example Output:
[-10.5, 6.0, -35.5, 38.0, 63.0, 0.5, -63.5, 3.5, 70.0, 42.5, 28.5, -25.0, -10.0]
