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: [60, -37, 70, -47, -91, -82, -29, 31, 6, -21, 35, -35, -8, 33, 92]

Solution: [11.5, 16.5, 11.5, -69.0, -86.5, -55.5, 1.0, 18.5, -7.5, 7.0, 0.0, -21.5, 12.5, 62.5]
