You are given that the following set of statements are true. (a) if an integer is even, then it is cosmological. (b) if a real number is cosmological, then it is not mystical. (c) if two real numbers are not mystical, then their product is mystical. provide a proof by contradiction for the following statement: it is true that at least one of v2 or 18 is mystical.

Ineed to know the rule for the sequence. plz !
