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: [-43, -47, 50, 31, 84, 3, 32, 51, 1, -24, 35, 91, -20, 78, 22]

Solution: [-45.0, 1.5, 40.5, 57.5, 43.5, 17.5, 41.5, 26.0, -11.5, 5.5, 63.0, 35.5, 29.0, 50.0]
