Slideshow introducing arithmetic and geometric sequences and showing how to write explicit formulas.
One slide contains a pattern-recognition warm-up.
Defines arithmetic and geometric sequences, then students go back to the warm-up problems and label them appropriately.
Introduces explicit formulas using patterns, gives one example of how to write them, then one practice problem. (Use with my Sequences Explicit Formulas Practice worksheet for more practice translating back and forth.)
Final slide is exit ticket asking where these skills could be useful in real life, and asking students to self-assess.
