Mathematics: arithmetic sequences
A math StudyPack organized around formulas, procedures and typical errors.
- Arithmetic sequence A sequence where each term differs from the previous one by the same constant difference.
- nth term formula a_n = a_1 + (n - 1)d, where d is the common difference.
- Common mistake Using n instead of n - 1 when counting how many differences separate a_1 from a_n.
