Determine the 28th term of the sequence -242, -251, -260

I got -512 because the pattern is adding -9.

I hope this helps! :D

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.
