About This Chapter
Mathematical Sequences: Chapter Summary
To answer number operations questions on the SAT level 1 mathematics subject test, you'll need an ability to work with mathematical sequences. Let our instructors show you how with lessons designed to help you:
- Identify terms in a sequence
- Find and classify an arithmetic sequence
- Find and classify a geometric sequence
Instruction is delivered in the form of short videos that feature tags you can use to quickly and easily access the content you're looking for, whether it be formulas for finding terms in a sequence or suggestions for identifying the common difference and common ratio. Links to supplementary text lessons are also included in the video transcripts if you'd like to get a better idea of what these and other mathematical terms mean. The multiple-choice quizzes at the end of each lesson can help assess your understanding of the material.
Mathematical Sequences: Chapter Objectives
The SAT level 1 mathematics subject test lasts an hour and consists of 50 multiple-choice questions; around 10%-14% of them are found in the number and operations content domain. To be successful on this part of the test, you'll need a solid understanding of number theory, complex numbers, ratios, proportions, matrices and sequences. If you need to brush up on this latter topic, lessons included here are designed to help you do just that.
Scores on the level 1 mathematics subject test can be used to demonstrate you academic talent to college admissions departments and make yourself stand out from the crowd. You can also use them to meet admissions recommendations or requirements and, in some cases, test out of introductory math classes.
1. What is a Mathematical Sequence?
Math is often the most fun when it acts like a puzzle to be solved. The branch of math where this is the most true involves sequences. Get an introduction to the basics and important vocabulary, as well as learn where sequences appear in nature!
2. How to Find and Classify an Arithmetic Sequence
Arithmetic sequences are everywhere, and with a few tricks you learn here, you could end up looking like a psychic the next time you go to a movie or a football game!
3. Finding and Classifying Geometric Sequences
Want your YouTube video to get a lot of hits? Besides including a cute baby or an adorable cat, getting your video to have a big common ratio is the key. Learn what I'm talking about here!
