What is the 30th term of the arithmetic sequence -8,-11,-14,-17,-20,......?
Since you are looking for the 30th term and the common difference is -3,
start with the first term, -8 and subtract 3 twenty-nine times to get to the 30th term. -8 - 3(29) {start with -8 and subtract 3, 29 times} = -8 - 87 {multiplied -3 by 29} = -95 {subtracted} -95 is the 30th term Ask Algebra House
