Question

Find the 12th term of on A.P. 16,11,6...........?​

Answer 1

Answer:

Give AP is

16, 11, 6,...........

In this AP

First term = a = 16

common difference = d = - 5

As

12th term of any AP having first term a and common difference d is given by

$a_{12} = a + 11d$

So,

12th term of given AP will be

$a_{12} = 16 + 11 \times ( - 5) \\ \\ a_{12} = 16 - 55 \\ \\a_{12} = - 39$

So,

So, 12th term of the given AP is -39.
