Teacher: 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].
Teacher: Now, understand the problem? If you are still confused, see the following example:
[-4, 7, 3]
Solution: [1.5, 5]
Reason: 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 instance: [0, -45, 44, -4, -58, -52, -72, -46, 35, -83, -25]
Student:
[-22.5, -0.5, 20.0, -31.0, -55.0, -62.0, -59.0, -5.5, -24.0, -54.0]
