Question

Please solve it question no. 14

Answer 1

the answer would be ----
2/3
as 2/81 is divided by 1/3,2/27 is divided by 1/3,2/9 is divided 1/3.....
HOPE IT HELPS U.....

Answer 2

Given Sequence is (2/81), (2/27), (2/9)... 54.

⇒ Here, Last term = l = 54.

⇒ Common ratio = r = (2/27) * (81/2)

                                  = 3.

⇒ n = 4.

We know that nth term from the end = l(1/r)^n - 1

4th term from the end = 54(1/3)^4 - 1

                                     = 54(1/3)^3

                                     = 54(1/27)

                                     = 2.

Therefore, 4th term from the end of the GP = 2.

Hope it helps!
