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: [52, 73, -83, 42, -60, 60, -88, 56, -48, 34, -30, 79, 47, -74, -93]

Solution: [62.5, -5.0, -20.5, -9.0, 0.0, -14.0, -16.0, 4.0, -7.0, 2.0, 24.5, 63.0, -13.5, -83.5]
