This math topic focuses on identifying the first values from a rule for decreasing arithmetic patterns. It includes various problems where a starting number is given, along with a rule to subtract a constant amount. Students must select the correct sequence of numbers that follow this pattern from multiple choices provided. Each problem requires understanding and applying the concept of an arithmetic sequence where the common difference is negative, reinforcing skills in pattern recognition and basic arithmetic operations within sequences.
