Answer:which term?

the question is not proper

please add my answer to the brainelist answers and follows up me.

Given 9th term = 0

a + 8d = 0

a = -8d

29th term = a + 28d = -8d + 28d = 20 d

19th term = a + 18 d = -8d + 18 d = 10d

Ratio of 29th and 19th term = 20d/10d

= 2/1

the answer is 2:1.
