Q. Write an expression to describe the sequence below. Use nn to represent the position of a term in the sequence, where n=1n = 1 for the first term.\newline–1,0,1,2,...–1, 0, 1, 2, ...\newline_____
  1. Start and Increase Pattern: The sequence starts at −1-1 and increases by 11 each time. To find the nnth term, we start with the first term and add 11 less than the position number, because the first term is at position 11 but is −1-1, not 00.
  2. Find nth Term Formula: So, the expression is the first term (−1-1) plus the position number (nn) minus 11. That's −1+(n−1)-1 + (n - 1).
  3. Simplify Expression: Simplify the expression: −1+n−1-1 + n - 1 turns into n−2n - 2.
