This topic involves finding the first three terms of arithmetic sequences from given algebraic expressions. Each problem presents a formula for an arithmetic sequence where the variable (like z, b, m, c, y) starts at 1. Learners need to substitute these starting values into the formulas to determine the sequence's first three terms. The problems are diverse in the arithmetic operations involved and test the ability to evaluate and comprehend the patterning in basic arithmetic sequences.
