Number Sequences - Arithmetic, First Terms (Level 2)

This math topic focuses on finding the first three terms of arithmetic number sequences. Each problem presents a different linear formula, and students must calculate the sequence by substituting integer values starting from 1. These problems help develop skills in handling arithmetic sequences, understanding algebraic expressions, and applying substitution in formulas to find sequential terms. The broader context of these exercises is an introduction to patterning and number patterns.
