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: [11, 8, -57, 58, -86, -93, 35, -94, 67, -71, -80, 4, -65, -84]

Solution: [9.5, -24.5, 0.5, -14.0, -89.5, -29.0, -29.5, -13.5, -2.0, -75.5, -38.0, -30.5, -74.5]
