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].

Input: Consider Input: [-99, 100, -53, -61, 64, -96, 13]

Output: [0.5, 23.5, -57.0, 1.5, -16.0, -41.5]


Input: Consider Input: [-57, -27, -20, 4, -82, 58, -39, 92, 64, -68, -21]

Output: [-42.0, -23.5, -8.0, -39.0, -12.0, 9.5, 26.5, 78.0, -2.0, -44.5]


Input: Consider Input: [-72, 92, -72, -67, 70, 94, 96, 33, 33, 6]
