What is the 15th term in the arithmetic sequence described by this explicit formula? an = 63 + (n – 1)(–7)

carmelle:

To find the 15th term, you basically have to plug in the number `15` for `n` in this sequence. = 63 + ( `15` – 1 )(–7) So first, you have to do solve for what is in the parenthesis according to PEMDAS. so what is 15 - 1?
