Number Sequences - Arithmetic, First Terms

This math topic focuses on identifying the first three terms of arithmetic number sequences given specific starting points and sequence rules. Each problem provides a mathematical expression that defines the sequence and asks learners to compute the sequence starting with a given initial term. The learners then select the correct sequence from multiple choices presented for each question. This skill is part of a larger unit on introductory number patterns, emphasizing pattern recognition and basic arithmetic operations in sequence construction.
