This lesson focuses on using the nth term of a sequence to generate terms of a sequence and finding first- and second-difference sequences. Students write terms of sequences from pictorial and word descriptions and by using a given formula for the nth term, including formulas with quadratic rules and with variables in the denominator. Students conclude the lesson by finding the first- and the second-difference sequence for a sequence with a quadratic rule.
