It requires 200 terms to approximate Pi to 2 decimal places.

how many terms would it take to get to 6 decimal places? 600? or is it a increasing value?

Hi mp.nighthawk, welcome on Daniweb!
It would take you 2000 terms to calculate pi to 3 decimal places.
Try it out with the C# code given in the previous thread.
Do you see the pattern?
