Tara has an antique sewing machine from her grandmother. it is currently worth $350. every year, it’s value increases by $20. if tara is 13 now, how much will the sewing machine be worth when she is 30 years old.

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
