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: [14, -60, -55, -36, -1, -26, -11, 30, -37, 60, -66, 97]
A:
[-23.0, -57.5, -45.5, -18.5, -13.5, -18.5, 9.5, -3.5, 11.5, -3.0, 15.5]
