Sequences
To say it explicitly—put the terms in order. Pupils learn about the two main sequences, arithmetic and geometric and discover the general explicit formulas for both types. Using the formulas, learners then calculate specific terms of the...

Recursive Formulas
Write formulas that depend upon previous terms. Individuals watch a video that explains how to create a recursive formula based on a sequence of numbers. Learners find out how to determine whether a sequence is geometric or arithmetic...

Sequences
Develop a sequence of descriptions. Learners watch an introduction to sequences, their notations, and how to graph them. Pupils use full sentences to describe the sequence and how to get from one term to the next, without needing to...

Explicit Formulas
Find a faster way to determine the 100th term of a sequence. Learners watch a video providing instruction on a way to find the nth term of a sequence—without writing down all the previous terms. Scholars create explicit formulas for...

The nth Term for Fractional Sequences
The process for sequences doesn't change just because the terms are fractions. Given a sequence composed of fractional terms, pupils see how to write an explicit algebraic formula to represent the sequence. The video then shows them how...

Patterns and Sequences
What comes next? Scholars view a video that explains how to determine the next figure in a pattern. They connect the figures to arithmetic sequences and write explicit formulas for the patterns.

Sequences Missing Terms
Something missing from your knowledge of sequences? Viewers of a short YouTube video learn how to find missing values in a sequence. These include arithmetic and geometric sequences, as well as patterns that do not fit either category.

Can You Find the Next Number in This Sequence?
It is not your typical type of sequence. The resource presents a number sequence that is not generated using a mathematical formula. Saying a terms digits creates the next term in the sequence, allowing learners to see patterns these...

How Infinity Explains the Finite
Using infinity to prove a sequence is finite sounds counter-intuitive, doesn't it? Scholar learn about hereditary base notation and the Goodstein sequence. They discover that proving the Goodstein sequence is finite requires infinite...

Introduction to Sequences
Finding patterns—seems easy enough. High schoolers learn the definition of a sequence in a concept video. Four problem videos then cover finding a particular term of a sequence given an explicit formula and identifying arithmetic...
