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: [71, 45, -12, -73, 41, -51, 24, -21, -87, -29, -87, 62, 74, -50]

Solution: [58.0, 16.5, -42.5, -16.0, -5.0, -13.5, 1.5, -54.0, -58.0, -58.0, -12.5, 68.0, 12.0]
