You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
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].

[-4, 7, 3]
Solution: [1.5, 5]
Why? 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.

New input: [-85, -48, -49, -68, -3, 57, 3, -48, 95, 45, 66]
Solution:
[-66.5, -48.5, -58.5, -35.5, 27.0, 30.0, -22.5, 23.5, 70.0, 55.5]
