11. Find patterns in application problems involving series and sequences, and develop recursive and explicit formulas as models to understand and describe sequential change.

Examples: fractals, population growth

This is an activity used to introduce a lesson on explicit and recursive formulas for a sequence from a pattern. Students are asked to examine a pattern and find a formula to describe the sequence in the pattern. They will then determine if they wrote an equation that is recursive or explicit using the given definitions of both.

11. Find patterns in application problems involving series and sequences, and develop recursive and explicit formulas as models to understand and describe sequential change.

Examples: fractals, population growth

This Desmos Activity will lead students to sort patterns and write formulas for each pattern.  They will then sort the formulas into either recursive formulas or explicit formulas.

Examples: fractals, population growth

This learning activity is an assessment activity that uses an exit ticket to ask students to write both a recursive and explicit formula for a simple application problem.
