2-72.

Choose one of the sequences in problem 2-71 for which you determined that 447 is *not* a term. Write a clear explanation (that an Algebra 1 student would be able to understand) describing how you can be sure that 447 is not a term of the sequence. Homework Help ✎

447 = 24 − 5*n*

423 = −5*n*

−84.6 = *n*

In order for a term to appear in the sequence, *n* must be a positive integer. Since the term, '447' is neither, it does not appear in the sequence.
