# Superscript and subscript, to immediate right of symbol without distortion

I want to have an output like this

The closest I have come is with code ${A^{\leftarrow}}_(x, y, z + n)$ that gives me something like

where the subscript is way of the mark. Trying something like this $A^{\leftarrow}_(x, y, z + n)$ gives even a greater distortion like this

.

I have tried using \displaystyle but not sure how to get the syntax correctly, to make it happen. Display style seems to work with things like limits or sums, and I am not sure how I could bend them to my needs. Any leads would be helpful.

\documentclass{article}
$A^{\leftarrow}_{(x, y, z + n)}$
