Answer:32
Step-by-step explanation:
Since 5 dark colors are equal to 8 light colors, see how many times 5 goes into 20. 20/5=4. So now multiply 8 with 4. 8x4=32.
Answer:
Step-by-step explanation:
From your characteristic equation, your recursive equation is

the general solution:

The initial conditions are

For f(0) = 1, that is

For f(1) = 3, that is


From (*) and (**) you solve for A and B
you have A = 4/7 and B= 3/7
Replace A, B into the general one, you have the particular solution for the given condition
