Question

Find the next term in the following sequence:
$297$, $99$, $33$,

Answer 1

Given sequence: $297$, $99$, $33$, _____
Need to find: $4^{\text{th}}$ term

By observing the pattern of the above sequence, we get
$297÷3=99$,
$99÷3=33$,
$33÷3=\underset{–}{11}$

We can summarize the pattern as
$\text{Next term}=\text{Previous term}÷3$

Hence,
$4^{\text{th}}\text{term}$
$=3^{\text{rd}}\text{term}÷3$
$=33÷3$
$=\underset{–}{11}$
