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: [-4, 7, 3]
Example output: [1.5, 5]
Example explanation: To create the answer, we should first calculate the average of -4 and 7, that is: (-4 + 7 ) / 2 = 1.5, so the first element of the answer is 1.5. Then, we need to calculate the average of 7 and 3, that is: 5. So the second element of the answer is 5.
Q: [1, -64, 72, 62, -38, 29, -93, 75, -71, 49, -41, 33, 73]
A:
[-31.5, 4.0, 67.0, 12.0, -4.5, -32.0, -9.0, 2.0, -11.0, 4.0, -4.0, 53.0]
