Patterns and Sequences

This video shows an example of writing an algebraic equation for the pattern of blocks that grows at each iteration. Sal shows how to find the pattern by looking at the number of iterations and blocks. He then continues this example by...

Faced with a series of numbers, we need to find the following few values of the sequence. This short video shows an example of finding the following values in a sequence where we must find the pattern of adding a specific number each...

This video looks again at finding the algebraic pattern in sequences. In the example, we are looking at a figure where several toothpicks (or lines) are added each time, and you need to find how many toothpicks will be in the 50th...

Learners who view this video should gain a better understanding of the difference between a geometric sequence and an arithmetic sequence. The video includes an example of each, with step-by-step instructions on how to figure out which...

Briefly show your class or individual learners how to find the common difference in an arithmetic sequence. A quick and simple video, this resource should guide pupils toward understanding the concept of common difference. Appropriate...

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.

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.
