Arithmetic Sequence

Find the 59th term of the arithmetic sequence 26, 17, 8,.....?

---

In an arithmetic sequence, there is a common difference among the terms, or a number you are adding each time you move from term to term.

In 26, 17, 8, ......the common difference is -9.

To get to the 59th term, start with the first term, 26, and subtract 9 fifty-eight times.

26 + 58(-9) {starting with 26 and subtracting 9 fifty-eight times}
= 26 - 522 {multiplied 58 by -9}
= -496 {subtracted}
