Do you get how to do this question?
 
A Pendulum swings through an arc of 120 cm (Swing #1)
With each further swing, the arc length is reduced by 15 %
 
a) State the growth factor
b) calculate the length of the arc in Swing # 4
 
I think I'm supposed to use this formula:
 
Tn = ar^n-1
 
Tn is supposed to be the term number. a is the first term, and I think the percentage is supposed to go in for r.
