Given the sequence tn defined recursively below, find t4.
Alina [70]

Answer:

t_4 = 20

Step-by-step explanation:

The base case in the recursive function are:

t_1 = 1

t_2 = 2

The recursive case is equal to:

t_n = 2t_{n-1} + 3t_{n-2}

So replace t_n for t_4:

t_4 = 2t_{3} + 3t_{2}

In the new expression t_2 is a base case so you don't have to worry for that part, but t_3 is still the recursive case so evaluate again in t_n

t_3 = 2t_{2} + 3t_{1}

t_2 and t_1\\ are define as base cases so you replace for it's numbers:

t_3 = 2(2) + 3(1) = 7

Now return to t_4 and replace for the new values:

t_4 = 2(7) + 3(2) = 14 + 6 = 20

So the final answer is 20
