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: [-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: [29, -92, 6, -24, -12, 98, 69, 26, -32, 70, 37]
Example Output: [-31.5, -43.0, -9.0, -18.0, 43.0, 83.5, 47.5, -3.0, 19.0, 53.5]

Example Input: [-83, -27, -99, 92, -94, -24, -40, -68, -44, -70, 15, 80, -62, -39, 89]
