What is the answer for this?

The general formula for nth term of given sequence is:

Step-by-step explanation:

Given sequence is:

54,18,6.....

In order to write the general formula of a sequence, first of all the common ratio has to be found. Common ratio is the ratio between consecutive terms of a geometric sequence.

The general formula is:

Putting the values of a1 and r

Hence,

The general formula for nth term of given sequence is:

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
