What is the ninth term of the arithmetic sequence defined by the rule below?
A(n) = –14 + (n – 1)(2) answer 2
how did you get the answer
To find the ninth term of the arithmetic sequence, we substitute the value of n as 9 in the formula A(n) = –14 + (n – 1)(2):
A(9) = -14 + (9 - 1)(2)
A(9) = -14 + 8(2)
A(9) = -14 + 16
A(9) = 2
Therefore, the ninth term of the arithmetic sequence is 2.
