8th Grade Arithmetic and Geometric Sequences Worksheets

An arithmetic sequence adds the same common difference d each time, and a geometric sequence multiplies by the same common ratio r. There are 20 sheets for 8th grade here, each with an answer key and a worked example at the top. Classify Sequences With Negative Terms starts with lists like −5, 10, −20, 40, −80, Geometric Sequences With Fraction Ratios works with ratios such as −2/5, and Find the 50th and 100th Terms uses first term + (n − 1) × d. Two mazes, a card sort and a riddle let students check their own answers.
