Question

What is the ninth term of the arithmetic sequence defined by the rule below? A(n) = -14 + (n - 1)(2)

Answer 1

To find the ninth term of the arithmetic sequence defined by the rule A(n) = -14 + (n - 1)(2), we substitute n = 9 into the formula to obtain:

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.
