yeah but i didn't use a formula. i just didn't in my head but need work to show

anonymous · Answer

ok well, think of all the possibilities 18,81/27,72/36,63/45,54

anonymous · Answer

those are all of them and then you take the lower number multiply by three and add one and see if the larger number fits, there is no "equation" because the concept of "reversing" a number is not possible to show algebraically
