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.\newline60,120,180,240,…60, 120, 180, 240, \ldots\newline_____
  1. Write Expression Using nn: Now, let's write the expression using nn for the position of the term.\newlineThe first term is 6060, and the common difference is 6060, so the nnth term is 60+(n−1)×6060 + (n - 1) \times 60.
  2. Simplify the Expression: Simplify the expression. 60+(n−1)×60=60+60n−60=60n60 + (n - 1) \times 60 = 60 + 60n - 60 = 60n.
