30th card:

Apparent Price = 230-1 = 229 = 536,870,912 Gold

Actual Price = 2*30 = 60 Gold Ops, I made some mistakes, let me explain with math:

The progression is 2, 4, 6, 8, 10, 12, 14...

a1=2

a2=a1+2=4

a3=a2+2=a1+2+2=a1+2*2=6

a4=a1+2+2+2=a1+2*3=8

So, the formula is an=a1+2*(n-1)

Example: a27=a1+2*(27-1)=2+2*26=2+52=54
