If no one is responding, it's because we don't understand the problem.
Could you state the original problem?
Could somebody please solve y_t+1=0.5y_t+3 for me (?)
by using the iterative method (*)
t=0,1,2 & 3 (#)
(?) .What do you mean by "solve"?
. . . .Do they want a "closed form"?
Also, a few spaces and parentheses would help us read what you wrote.
. . I would guess that it is: .
(*) .We need to know what your teacher/course/textbook
. . . .means by the "iterative method".
(#) .This is strange.
. . . .We're involved with only the first four terms?
I would conjecture that they wants us to list the first four terms.
. . . .But they are expected to give us the first term,
