Patterning - Term Value from Equation for Decreasing Arithmetic Pattern (Level 3)

This math topic focuses on determining term values from equations for decreasing arithmetic patterns. It covers advanced exercises which include calculating specific terms from given equations where the sequence decreases at a constant rate. Each problem presents an equation, and students must find the corresponding term value for a specified position \( n \) in the sequence. This skill is crucial for understanding and manipulating arithmetic sequences, particularly those that decrease, and forms part of a broader unit on "Patterns and Sums."
