Do you know how to solve algebra? If so just solve for X. If you get an invalid equation then 0 solutions, if you get x equaling 1 number then 1 solution, if you get x equaling 2 numbers then 2 solutions, and so on.
The general term of a geometric sequence is
an = a1·r^(n-1)
Fill in the given numbers and do the arithmetic.
a12 = 18·2.1^(12-1)
a12 = 63,049.95009759978
