Answer:
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:

A and B because they both have the same angle
