This test comes in 3 different versions. Forms A and B are equal in difficulty. Form C assesses the same concepts as the other forms, but it is intended for students with IEP accommodations. Form C is roughly half the length with slightly easier questions. The following topics are assessed on all 3 forms: identifying arithmetic sequences, finding common differences, writing explicit formulas, finding the nth term, differentiating series and sequences, writing sequences as series, finding the sum of an arithmetic series, and using summation notation to write an arithmetic series. An answer key is included for each form of the test.
