Answer:
A term at position n can be expressed as \[2*3^{n-1}\]
Explanation:
The given geometric sequence is 2, 6, 18, 54, …
Starting term = 2
Second term = 6
So second term is 3 times the first term.
Similarly, Third term = 18
This is 3 times the second term, that is , 3 * 6
Fourth term is is 54.
This is 3 times the third term, that is , 3 * 18
Generalizing, a term in the sequence can be expressed as \[2*3^{n-1}\]
where n represents the position of the term in the sequence.
