Find the ninth term in the sequence given by the formula an = 3n + 1, where an is the value of the term and n is the term number. Then, find and graph the first 5 terms in the sequence.
1. Determine whether this is an explicit formula or a recursive formula. 2. Find the first 5 terms of the sequence. 3. Create ordered pairs from the sequence. 4. Plot the ordered pairs.
