Recall that a sequence of numbers forms an arithmetic progression if the difference between every pair of consecutive numbers is the same. For example, (-5, -1, 3, 7, 11] forms an arithmetic progression since the difference between every neighbor is 4. On the contrary, [5, 10, 15, 24, 29] is not an arithmetic progression since the difference between some consecutive pairs is 5 or 4. A sequence that has exactly one number is considered arithmetic, too. Testing: Write a function called arithmetic that takes as input a list of numbers and returns True if the numbers of the list form arithmetic progression. And False otherwise >>> arithmetic( [-5, -1, 3, 7, 11]) True >>> arithmetic ([0, -1, 3, 7, 11]) False >>> a = [5, 10, 15, 24, 29] >>> arithmetic(a) False >>> arithmetic(a[:3]) True
