The argument form described, "If I move to Texas, I will need air conditioning. I don't need air conditioning. So I didn't move to Texas," is an example of modus tollens. Modus tollens is a logical argument form that infers the denial of the consequent of a conditional statement. In this case, the conditional statement is "If I move to Texas, I will need air conditioning," and the consequent is "I will need air conditioning." The argument concludes that since the person doesn't need air conditioning, they didn't move to Texas.
