Question 1

What is the general form of a linear non-homogeneous recurrence equation?

a(n) = c_1*a(n-1) + c_2*a(n-2) + F(n)
a(n) = F(n)
a(n) = 2*a(n-1)

💡 Hint: Look for the version that includes both previous terms and F(n).

Question 2

True or False: A homogeneous equation does not include any function F(n).

True
False

💡 Hint: Consider the definitions we've discussed.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given the recurrence relation a(n) = 2*a(n-1) + n^2, derive the general solution.

💡 Hint: Focus on the polynomial degree and ensure your guesses are structured correctly.

Challenge 2 Hard

If F(n) includes an exponential function not part of the characteristic roots, how would you derive the particular solution?

💡 Hint: What structures might connect well without duplicating characteristics?
