Number Series Practice Test for Grade 8 CogAT

Posted on November 15, 2025

Do numbers seem like a mystery to your child, or can they spot patterns in a flash? 

The Number Series section of the CogAT Grade 8 Quantitative Battery challenges students to uncover the rule behind a sequence and predict the next number. 

In this section, students are presented with a series of numbers that follow a specific rule—such as addition, subtraction, multiplication, division, or a combination. Their task is to determine the pattern and identify the missing number. This question type evaluates numerical reasoning, pattern recognition, and logical thinking, all essential for success in gifted assessments. 

With the Gifted Test Prep App, your child can practice targeted Number Series questions designed specifically for Grade 8. Each question strengthens their ability to analyze sequences, apply rules, and solve problems efficiently under time constraints. 

We’ve included a free Number Series Practice Test for CogAT Grade 8 below. These examples mirror the format, difficulty, and reasoning style of the actual exam, helping you assess your child’s current ability and identify areas for improvement.
