3. VOCABULARY
sequence
term
finite sequence
infinite sequence
arithmetic sequence
common difference
geometric sequence
common ratio

4. Arithmetic sequence: Each term is determined by ADDING a constant value to the previous term. This constant value is the common difference.
Geometic sequence: Each term is determined by MULTIPLYING by a *constant value to the previous term. This constant value is the common ratio.
*nonzero

5. Determine whether the sequence is arithmetic
