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: [22, -70, 38, -45, 54, -70, 52, 66, 24, -28, 72, -79, -21, -10, 39]

Solution: [-24.0, -16.0, -3.5, 4.5, -8.0, -9.0, 59.0, 45.0, -2.0, 22.0, -3.5, -50.0, -15.5, 14.5]
