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: [-37, 98, -14, -76, -70, 63, -22, -13, 13, -34, 87, -36, 61]

Solution: [30.5, 42.0, -45.0, -73.0, -3.5, 20.5, -17.5, 0.0, -10.5, 26.5, 25.5, 12.5]
