Question

Find the next term of the given sequence:
$81$, $27$, $9$, ____

• A. 3

Answer 1

The correct option is A 3
The below given sequence has a decreasing pattern, and it is decreasing rapidly. So, to get the next term, dividing the previous term by a number is one of the feasible options.


After observing the pattern in the given sequence, we find:


$\therefore \text{Next term = Previous term}÷3$

Hence,
$4^{\text{th}}$ term
$=3^{\text{rd}}$ term $÷3$
$=9÷3$
$=3$
