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: [100, 82, 48, -85, 91, -94, 53, 91, 0, 71, 92, 0, -43, 17, 0]

Solution: [91.0, 65.0, -18.5, 3.0, -1.5, -20.5, 72.0, 45.5, 35.5, 81.5, 46.0, -21.5, -13.0, 8.5]
