For n=1, 3^(n-1)/10 = 1/10

For n=2, 3^1/10 = 3/10

For n=3, 3^2/10 = 9/10

For n=4, 3^3/10 = 27/10

The ratio of successive terms is 3.

I don't know why you wrote "bracket" at the end of your question.

there are two brackets, one on each side of the problem. The ratio was right thank you! But it said the n=1-4 was wrong?
