Find the common difference (d), then find the indicated term of the sequence.

-2, - 9,-16, - 23, ... find the 19th term

-128

Step-by-step explanation:

d = 2 term - first term = - 9 - (-2) = - 9 + 2 = - 7

a = - 2

nth term = a + (n-1) * d

19th term = - 2 + (19-1) * (-7)

= - 2 + 18 * (-7)

= - 2 - 126

= - 128
