Recursive Challenge Problem—The Double and Add 5 Game
As a continuation of a previous lesson, this activity builds on the concept of calculating the terms of a sequence. Pupils are challenged to determine the smallest starting term to reach a set number by a set number of rounds. Notation...

Arithmetic and Geometric Sequences
Old mathematicians never die; they just lose some of their functions. Studying sequences gives scholars an opportunity to use a new notation. Learners write functions to model arithmetic and geometric sequences and use them to find new...

Sequences Represented as Functions
What comes next? Starting with concrete drawings and advancing to using function notation, learners work together to solve problems involving sequences. They predict the nth term in a sequence and write sequences in function notation.

How Do You Find the Nth Term in an Arithmetic Sequence?
To find the 20th term in an arithmetic sequence, use the secret formula. What secret formula? It's: a sub n equals a sub one plus parentheses n minus one close parentheses times d. Got that? No? The watch this video to learn about the...
