Patterning - Term Value from Rule for Decreasing Arithmetic Pattern (Level 1)

This math topic focuses on finding term values in decreasing arithmetic sequences. Skills practiced include identifying the nth term from a given rule, where a starting number is progressively decreased by a fixed amount to find subsequent terms. Each question provides a starting number and a decrement value, tasking students with calculating a specific term's value. The exercise enhances understanding of arithmetic patterns and term calculation in progressively descending sequences.
