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.
