Question: Consider the recursive formula u0 = 450, un = 0.75un-1 + 210 where n 1 a. Find u1, u2, u3, u4, and u5. b.

Consider the recursive formula u0 = 450, un = 0.75un-1 + 210 where n ≥ 1
a. Find u1, u2, u3, u4, and u5.
b. How can you calculate backward from the value of u1 to u0, or 450? In general, what operations can you perform to any term in order to find the value of the previous term?
c. Write a recursive formula that generates the values of u5 to u0 backward.
