Ch 13: Mathematical Sequences

About This Chapter

Prepare for the SAT level 1 mathematics subject test with this chapter's video lessons and quizzes. Instructors show you how to find common ratios and differences and write formulas for arithmetic and geometric sequences.

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.
