# Sequences

## Identify arithmetic sequences

A sequence is given: 7, 5, 3, 1, -1,...
1) Is this sequence arithmetic or geometric? Explain
2) Write a recursive rule and an explicit rule
for each of the following sequences.

For
each rule, generate the first 5 terms of the sequence that is defined. In each
case,

**is an integer and***n***≥ 2. a. f(1) = 4 f(***n***) = 5 + f(***n***– 1) b. f(1) = –3 f(***n***) = –2 × f(***n***–***n*## New Resources
