Question

Which term of the A.P. 27, 24, 21,…..is zero?​

Answer 1

Answer:

N=10

Step-by-step explanation:

By using formula a +(n-1)d=0

27+(n-1)-3 =0

27+3n+3=0

30+3n=0

3n=-30.

N= - 30 /3

n=-10. N=10

I hope it will help you

Answer 2

Answer:

given,

An = 0

a = 27

d= -3

we know that,

An = a + (n - 1 )d

0 = 27 + (n - 1 )(-3)

0 = 27 - 3n + 3

0 = 30 - 3n

-30 = -3n

-30/-3 = n

n = 10

hence, 10th term of AP is 0.
