non-homogeneous recurrence with a constant for F(n)
If I have a non-homogeneous recurrence with a constant for F(n):
The associated homogeneous solution is
But what is the 'particular' solution?
If I try to calculate particular solution through
, I am getting:And at the end I receive:
Which is obviously not a correct answer...
What am I doing wrong?
