Question

which term of the AP 27, 24, 21,.....is 0. please write the right answer please help me please bro please help me.​

Answer 1

AP: 27,24,21.....

a = 27

d = -3

an = 0

n = ?

an = a+(n-1)d

0 = 27+(n-1)-3

-27/-3 = n-1

n = 9+1

n = 10

So, 0 is the 10th term of the AP.

Hope it helps......

Answer 2

Solution:-

In the given AP , we have

First term = 27 and

Common difference = 24 - 27 = -3

: - a = 27 and d = 4

Let its nth term be 0 , Then

$\to \bf \: T_n = a \: + \: (n - 1)d$

$\to \bf \: T_n = 0$

=> 27 + ( n - 1 ) × -3 =0

=> 27 - 3n + 3 = 0

=> 30 - 3n = 0

=> 3n = 30

=> n = 10

Hence the 10th term of the given AP is 0
