What's an Arithmetic Sequence?

Arithmetic and geometric sequences are linear and geometric patterns. Help pupils understand the relationship and see the connection with an activity that asks them to write the rules and classify the patterns correctly. A sorting...

Fibonacci is an interesting sequence that forms some unique patterns. Learners explore sequences that do not have the typical arithmetic and geometric patterns. They identify the pattern and find the next consecutive terms....

Natural human interest in patterns and algebraic study of function notation are linked in this introductory unit on the properties of sequences. Once presented with a pattern or situation, the class works through how to justify...

Sal solves a problem from the AIME (American Invitational Mathematics Examination) that utilizes knowledge of arithmetic sequences to create a third sequence for which one needs to find the eighth term of. This is a pretty complicated...

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...

Common difference? Sounds like an oxymoron. It's a math term used to describe a pattern that may occur between a series of numbers. Watch this video and the instructor will explain what the term means as it is applied to an arithmetic...

2, 4, 6, 8, who do we appreciate? Do the numbers in this sequence make it an arithmetic sequence? Watch this video and find out.
