Answer 1

Which field of Mathematics?

Answer 2

It doesn't say

Answer 3

What does un, u, U2 and u0 represent?

Answer 4

did you mean \(u_n\) as in u_n?

Answer 5

Yeah didn't know how to do that but

Answer 6

Did you mean \(\Large u_{n+1}=5-2u_n\)?

Answer 7

Yeah

Answer 8

Please use brackets next time :)

\[u_2=5−2u_1\]\[u_1=5−2u_0\]

Answer 9

Now plug in \(u_2\) and find \(u_1\), then plug in \(u_1\) to find \(u_0\) :)

Answer 10

How do I plug u_2 in but

Answer 11

\[3=5-2u_1,\]solve for \(u_1\).

Answer 12

u1 = 1

Answer 13

u0 = 2
