Hi there!
The question gives us the rule A(n) = -14 + (n - 1)(2). We are asked to find the ninth term of the arithmetic sequence. To find this, all we have to do is plug in 9 for n. This gives us A(9) = -14 + (9 - 1)(2). Now, just simplify.
A(9) = -14 + (9 - 1)(2)
A(9) = -14 + 16
A(9) = 2
Therefore, the ninth term in this arithmetic sequence is 2. Hope this helped and have a phenomenal day!
