This math topic focuses on identifying arithmetic sequences and determining the algebraic expression that describes the sequence given the first three terms. It involves pattern recognition and understanding the relationship between consecutive terms in an arithmetic sequence, typically formatted as "What sequence, starting with a variable equals 1, are these the first 3 terms of?" Each problem is followed by multiple choices expressed in algebraic terms involving the sequence's starting variable. This aims to enhance skills in patterning and number patterns practice, primarily using linear relationships.
