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: [-66, 10, -38, -37, 26, -28, -93, -76, 72, -48, -1, 21, 25]

Solution: [-28.0, -14.0, -37.5, -5.5, -1.0, -60.5, -84.5, -2.0, 12.0, -24.5, 10.0, 23.0]
