This math topic focuses on identifying the rules for decreasing arithmetic patterns. The problems require selecting the correct rule that describes how sequences of numbers decrease. Each question lists a sequence of numbers, and the learner has to choose the right arithmetic rule from multiple options. These rules involve subtracting a fixed number from each term to reach the next one in the pattern. The problems challenge the learner's understanding of basic arithmetic operations and their application in recognizing patterns in sets of numbers.
