The first term in an arithmetic sequence is 5. The third term in the sequence is -1. The tenth term in the sequence is -22. Xavier said that the recursive formula for a sequence a(n)=an-1-3 could be described as, “to find the next term of the sequence, add -3 to the previous term.” Do you agree or disagree that this statement is equivalent to the explicit formula a(n)=-3n-12?
