13)1,722 pls give the answer step by step

table 3 represents a direct variation function. : )

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
