with explaination ​

Answer 1

Answer:

Step-by-step explanation:

Given,

A.P sequence :-

Correct sequence :-

12 , 9 , 6 , 3 ..

To Find :-

6th term of an A.P

Solution :-

12 , 9 , 3

First term of an A.P(a) = 12

Common difference(d) = 9 - 12 = - 3

9 - 6 = - 3.

d = - 3

As, we need to find 6th term , n = 6.

General form of an A.P :-

$t_n = a + (n - 1)d$

$\implies t_6 = 12 + (6 - 1)(-3)$

$= 12 + 5(-3)$

$= 12 - 15$

$= - 3.$

Since, 6th term of an A.P = - 3
