Question

Solve the recurrence relation for the variables indicated below:

bn = 8bn-1 - 15bn-2

b1 = 2

b2 = 16

If the explicit formula for the sequence is written in the form

bn = u(s1)n + v(s2)n

then find s1 and s2 .

anyone? pretty please?

Answer 1

bn = 8bn-1 - 15bn-2
b1 = 2
b2 = 16
If the explicit formula for the sequence is written in the form
bn = u(s1)n + v(s2)n
then find s1 and s2 , and u and v.

Answer 2

uh.. yea... that's kinda the question.... cause the answer isn't there....

Answer 3

oh my bad sorry

Answer 4

(i tried googling it too :D )

Answer 5

does this help en.Wikipedia.org/wiki/recurrence_relation#solving

Answer 6

not really... I need someone to guide me through it.... it's a discrete math problem and I can't figure it out...

Answer 7

I ended up finding S1 = 3, S2 = 5. a little more math leads to U1 = -1 and U2 = 1. those are the answers. done. closing question now.
