Answer:
f(3) = -10
Step-by-step explanation:
The formula given is f(n) = f(n − 2). f(n - 1)
For the first term in the quotient:
if n = 3 then substitute the result of f(3 − 2) = f(1) spot, which is given by the number -2.
for the second term in the quotient:
if n = 3 then substitute the result of f(3 − 1) = f(2) spot, which is given by the number 5.
Now combine this and you get:
f(3) = -2 * 5
f(3) = -10
