Write a predicate jumptwo/2 that is true when the first argument is two less than the second argument. ?- jumptwo (2, 4). true. ?- jumptwo (1, 2). false. What happens if you try jumptwo (X, Y) ? Why? Write a recursive predicate multiplylist/3 whose first argument is a list of integers, and whose second argument is the list of integers obtained by multiplying each integer in the first list by the third argument, which is an integer. ?- multiplylist ([1, 2, 3], X, 5). X = [5, 10, 15]. ?- multiplylist ([0, 5, 7], [0, 10, 13], 2). false. Try multiplylist ([1, 2, 3], [5, 10, 15], X). Would you want to use Prolog for an arithmetic-heavy application? Why or why not
