Which of the following is the is the nth term rule of the sequence 9, 1, -7, -15?
SOLUTION:
• We'll use the formula for arithmetic series. Thus, we need to identify the first term and the common difference.
• The common difference can be obtained when you try to subtract a particular term by its preceding term. Thus, our common difference is and . The first term is obviously, 9.
