Question

Find f(5) for this sequence:

f(1) = 2 and f(2) = 5, f(n) = f(1) + f(2) + f(n - 1), for n > 2.

f(5) = ______

Answer 1

please help me!

Answer 2

f(3) = f(1) + f(2) + f(2) = 2 + 5 + 5 = 12
f(4) = f(1) + f(2) + f(3) = 2 + 5 + 12 = 19
Similarly you simply substitute for f(5) = f(1) + f(2) + f(4) and you get the answer
