CPM Homework Help : CCA2 Problem A-67

Choose one of the sequences in problem A-66 for which you determined that $447$ is not a term. Write a clear explanation describing how you can be sure that $447$ is not a term of the sequence.

Example:

$447 = 24 − 5n$

$423 = −5n$

Can you make your own example?

Answer:

$-84.6 = n$

In order for a term to appear in the sequence, $n$ must be a positive integer.
Since the term ' $447$ ' does not yield a positive integer for $n$ , it does not appear in the sequence.
