Arithmetic Sequences, Functions, Equations and Graphs
Jan 21st, 2009 by Nick
Some students were having a hard time writing equations based on graphs in my Algebra class. They’re supposed to be able to write equations based on graphs using what they know about arithmetic sequences and using the formula for the nth term of an arithmetic sequence a1 + d(n – 1). Anywhoo, I’m gonna use this presentation in class while they practice tomorrow.
The general idea is to be able to talk about seeing the progression of y-values as a sequence and only changing the x-values by one.
