Detailed Solution

Given A.P. is

27, 24, 21, …

.
Here,

a = 27, d = − 3

.
We need to find which term of the given series is 0.
Let it be nth term.

∴ a n = 0

We know that nth term of A.P =

a + (n − 1) d = a n

.
Substitute the values in above equation,

27 + (n − 1) (− 3) = 0 27 − 3 n + 3 = 0 30 − 3 n = 0 3 n = 30 n = 10

Therefore 10th term of given A.P

27, 24, 21, … .

is 0.
The correct option is (2).
