ok I know this is a little (ok way) late but I need help with this question on series. I'm doing Question 10 of 2001 and I get all the way to the end and get this line.
Bn = 1000(1.06)^n - 1200(1.06^n - 1)
Right and then the next line is
Therefore Bn = 1200 - 200(1.06)^n
What? where's the 200 come from?
oh god i'm so screwed
