Find the value of u1, u2, and u3. Identify the type of sequence (arithmetic, geometric, or shifted geometric) and tell whether it is increasing or decreasing.
a. u0 = 16
un = (1 - 0.05)un -1 + 16 where n ≥ 1
b. u0 = 800
un = (1 - 0.05)un -1 + 16 where n ≥ 1
c. u0 = 50
un = (1 - 0.10)un -1 where n ≥ 1
d. u0 = 40
un = (1 - 0.50)un -1 + 20 where n ≥ 1
