# Thread: Pauline and her insurance scheme...

1. ## Pauline and her insurance scheme...

Hi, was just wondering if anyone could help me with a few questions, had a look all through my notes and there doesn't seem to be anything that I can use in these situations (there probably is, but you know when you get stuck you just cant seem to think it through straight!)

okay, so

C2:
6 The ammount of money which Pauline pays into and insurance scheme is recorded each day. The ammount which pauline pays in during the nth year is £Aη. The first three values of Aη are given by:

A1=800 A2=650 A3=530

The recorded amounts may be modelled by a law of the form

Aη+1=pAη+q

Where p and q are constants
a) Find the value of p and the value of q
b) Find the limiting value £V using and equation for V

2. So, 650 = p*800 + q
and 530 = p*650 + q

What's next?

Okay so from there I can take the equation 530 = p*650 + q from 650 = p*800 + q, meaning that I will be left with just P=xyz, then sub p back into the original thank you very much!
