Answer:
B. 5, 20, 80, 320.
Step-by-step explanation:
f(1) = 5
After the first rem, each term id 4 times the previous term, so:
f(2) = 4f(1) = 4*5 = 20.
f(3) = 4f(2) = *20 = 80
f(4) = 4(f3) = 4*80 = 320.
Divide by 3 on both sides:
Square root both sides:
Take away 3 from both sides:
Divide by 2 on both sides:
Answer:
121,000,000,000
