If you put a number in a magic box, it will give you a new number after three steps. In the first step , he will add $3$ with the number, then he will multiply the the result with a, then he will add $b$ with the result. If you give $39$ then you get $204$, If you give $420$ then you get $2109$, then if we give $2017$ then what will we get?
