There is no "d" in

Sn=(Ar(rn-1)/r-1

to make as the subject. Also we cannot tell whether
the n is a subscript or not.

I will guess what you might have meant.  If it's not,
then tell me in the reply form below and I'll get
back to you by email.

Make n the subject of the formula.

Multiply both sides by r-1
