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: [-4, 7, 3]
Example solution: [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.

Problem: [0, -85, 1, 64, 53, -80, 18, 45, 57, -84, -11, 80, -23, 91]

Solution: [-42.5, -42.0, 32.5, 58.5, -13.5, -31.0, 31.5, 51.0, -13.5, -47.5, 34.5, 28.5, 34.0]
