Question

which term of the A.p 27 , 24 ,21 ,..zero​

Answer 1

Answer:

10 th term will be 0 (zero)

Step-by-step explanation:

Given A.P : 27,24,21,..... find which term is 0

here, a = 27, d = t₂-t₁ = 24-27 = -3

       tₙ = a + (n-1)d

=>    0 = 27 + (n-1) (-3)

=>    0 = 27 +3 - 3n

=>    0 = 30 - 3n

=>    3n = 30

=> n = 30/3 = 10
