Answer 1

Answer:

111

Step-by-step explanation:

Ap: 3,15,27,39,....171

first term from last = a= 3

common difference =d=3-15=-12

Nth term= a+(N-1)d

6th term    =171+ (6-1)-12

                 =111

Answer 2

The 6th term from the last term​ = 111

Step-by-step explanation:

The given AP are:

3, 15, 27, 39, .............., 171

Here, first term (a) = 3, common difference (d) = 15 - 3 = 12 and

last term (l) = 171

To find, the 6th term from the last term​ = ?

We know that,

The nth term from the last term​ = l - (n - 1)d

The 6th term from the last term​

= 171 - (6 - 1)12

= 171 - (5)12

= 171 - 60

= 111

∴ The 6th term from the last term​ = 111
