Problem$$Carefully read the problem specification below:Problem SpecificationWrite a function named reverse$\_$arithmetic$\_$sequence that has three parameters, first,$$difference$,$ terms. Your code should work with data of$$any datatype provided as arguments.The function should:$1$Validate the provided parameter values $($see specification below$)2$Generate the sequence using the algorithm below$3$Return the generated sequence as a list.You will need to do some validation on the parameters provided:All parameter values must be integers$($in either int or str format$).$ If any of the parameters do not hold integer values, the function should return None.A valid first$$value must be between $50$ and $200($inclusive$).$A valid difference$$value must be greater than $1$ and less than or equals to $10.$A valid terms value must be between $5$ and $100($inclusive$).$If any of the three restrictions above are not met, the function should return False.Algorithm$1$Generate a list of numbers that begins with the$$first value. Each value in the list should be an integer $($datatype$)\mathrm{.}2$Each subsequent value in the list is calculated by taking the previous value and subtracting the difference to it $($refer to the test cases below as examples$)\mathrm{.}3$The$$number of items in the list should be equal to the value of terms.Skeleton Codedef reverse$\_$arithmetic$\_$sequence$($first$,$difference,terms$)$:$"""$ Test cases:$>>>$ reverse$\_$arithmetic$\_$sequence$(60,2,6)[60,58,56,54,52,50]>>>$ reverse$\_$arithmetic$\_$sequence$(100,5,10)[100,95,90,85,80,75,70,65,60,55]>>>$ reverse$\_$arithmetic$\_$sequence$(\text{'}50\text{'},2,5)[50,48,46,44,42]>>>$ reverse$\_$arithmetic$\_$sequence$(73,\text{'}3\text{'},7)[73,70,67,64,61,58,55]>>>$ reverse$\_$arithmetic$\_$sequence$(50,2,\text{'}5\text{'})[50,48,46,44,42]>>>$ print$($reverse$\_$arithmetic$\_$sequence$(73\mathrm{.}5,4,10))$ None$>>>$ print$($reverse$\_$arithmetic$\_$sequence$(85,4\mathrm{.}6,10))$ None$>>>$ print$($reverse$\_$arithmetic$\_$sequence$(100,4,10\mathrm{.}3))$ None$>>>$ reverse$\_$arithmetic$\_$sequence$(20,4,10)$ False$>>>$ reverse$\_$arithmetic$\_$sequence$(300,4,10)$ False$>>>$ reverse$\_$arithmetic$\_$sequence$(62,1,10)$ False$>>>$ reverse$\_$arithmetic$\_$sequence$(92,12,10)$ False$>>>$ reverse$\_$arithmetic$\_$sequence$(63,4,3)$ False$>>>$ reverse$\_$arithmetic$\_$sequence$(73,5,231)$ False$"""$ # TODO: Your code here# Call the code to run the doctestsimport doctestdoctest.testmod$($verbose$=$True$)$
