Question

Conjecture a formula for un=un-1-2 where u0=4

Answer 1

4-2*n

Answer 2

are yu sure that's typed right?

Answer 3

\[u _{n}=u _{n-1}+d\]

Answer 4

oh ok. so,\[u_{0} = 4 ?\]

Answer 5

\[u _{_{0}}=4\]

Answer 6

than it is 4+n*d

Answer 7

is this that you need?

Answer 8

I saw that the equation would be y=-2x +4 but need a general solution in terms of recurrence

Answer 9

un=un−1+d if this is the general formula that the answer should be u0 + n times d

Answer 10

y=-2x +4 this is the same as I wrote first just written as a function

Answer 11

yes but I need it in terms of previous

Answer 12

Use iteration (by hand or with your calculator) to explore the first few terms of each sequence.
ii. On the basis of (i), conjecture a formula for a solution u(n) of the general affine system with r=1:
(I) u0=c
(R) un=un-1+d for n > 0
