Term Value from Rule for Decreasing Arithmetic Pattern (Level 2)

This math topic involves practicing how to find specific terms in decreasing arithmetic sequences, where each term is derived by consistently subtracting a fixed number from the previous term. Problems require calculating the nth term based on starting values and specified rules for subtraction. Arithmetic sequences covered typically start with a defined number and consistently subtract 2, 3, 4, or 5 from each successive term to find values at different positions (n) in the sequence.
