Term Value from Rule for Decreasing Arithmetic Pattern (Level 3)

This math topic focuses on finding the value of a term in a decreasing arithmetic sequence. Each problem provides a starting number and a common difference by which the sequence decreases for each successive term. Students are tasked with calculating the value of a specific term in the sequence. This advanced exercise enhances understanding of patterns and sequences, requiring application of arithmetic operations and sequence rules.
