In advance sorry for the very collumn layout but I tihnk it makes the question a lot clearer.
un+1 = aun + b
u1 = 5,
u2 = 9.5,
u3 = 20.75
so
9.5= a(5) +b
20.75= a(9.5) + b
now I am not sure what to do from here one, should you combine both the equations or do a simultanious equation?
Combining
30.25 = 2a(47.5) +2b
x/2
15.125 = a(47.5) + b
15.125 - b = a(47.5)
(15.125 -b)/47.5 = a
I'm not sure if this is the right route since I have a and b on either sidebut I'm lost from here, any help would be appreciated:)
