10-1 Sequences as Functions Relate arithmetic sequences to linear functions. Relate geometric sequences to exponential functions.

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

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

Determine whether the sequence is arithmetic Determine whether the sequence is arithmetic. Write yes or no and explain.

Find the next four terms of the arithmetic sequence Find the next four terms of the arithmetic sequence. Then graph the sequence.

Determine whether the sequence is geometric Determine whether the sequence is geometric. Write yes or no and explain.

Find the next four terms of the geometric sequence Find the next four terms of the geometric sequence. Then graph the sequence.

Determine whether the sequence is arithmetic, geometric, or neither Determine whether the sequence is arithmetic, geometric, or neither. Explain your reasoning.
