You have written the problem one way, using An^2
and another way using A2n. These two different things would not be the same.
One implies a constant coefficient A, the other is strange because it's possibly the square of A2 --although this is just a guess.
Either way, you have not provided sufficient information.

Actually the correct is 2nd one the 1st I write because on keypad I couldn't write subscript. It is actually A and n is subscript where 2 is superscript of A

Well, we have to know something about the A sequence. All we can do is find An by taking square root of 30. That does not enable us to know n.
