This math topic focuses on identifying arithmetic sequences given their first three terms. Each problem presents a different sequence and asks students to determine the formula that describes it. The skills practiced include understanding sequence patterns, forming algebraic expressions for arithmetic sequences, and applying algebraic thinking to sequence identification. The problems involve a variety of sequences, each starting with a different initial term. Students must choose the correct sequence formula from multiple choices provided for each sequence. This topic is a part of a broader unit on number patterns.
