8. Find the first term of the pattern

A pattern of integers is generated by multiplying the previous term by \(-3\). If the \(5^{\text{th}}\) term in this sequence is \(-162\), track the sequence backward to uncover the first term.

 

Ans: 

 

First term \(=\) $i$

 

Sequence from first term \(=\) $i,i,i,i,i$
