This question legitimately confuses me.
I found that the formula for a geometric sequence is An=1800 x 0.9^(n-1)
How does one calculate the maximum value from that, however?
I do not understand how there is a maximum value for geometric sequences.

I think you mean a value which the sum of the sequence approaches but never reaches, called the sum to infinity. The formula ia a/(1-r)
So in your case a=1800 and r=0.9 so sum to infinity =1800/0.1 =18000. r has to be between -1 and +1 for a sequence to have a sum to infinity.
