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].
One example: [-4, 7, 3]
Solution is here: [1.5, 5]
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.

Now, solve this: [91, -34, 67, 22, -48, -33, -53, -29, -89, 18, 77, -87, 49, -69, -44]
Solution:
[28.5, 16.5, 44.5, -13.0, -40.5, -43.0, -41.0, -59.0, -35.5, 47.5, -5.0, -19.0, -10.0, -56.5]
