Complete question
Given the recursive formula shown, what are the first 4 terms of the sequence?
f(1) = 5 if n=1
f(n) = 4f(n-1) if n> 1
A) 5. 25, 100, 400
B) 5, 20, 80, 320
C) 5, 25, 125, 625
D) 5. 14, 60, 236
Get f(2)
f(2) = 4f(2-1)
f(2) = 4f(1)
f(2) = 4(5)
f(2) = 20
Get f(3)
f(3) = 4f(3-1)
f(3) = 4f(2)
f(3) = 4(20)
f(3) = 80
Get f(4)
f(4) = 4f(4-1)
f(4) = 4f(3)
f(4) = 4(80)
f(4) = 320
Hence the first 4 terms of the sequence are 5, 20, 80 and 320

Answer:
7%
Step-by-step explanation:
Step one:
given data
The original cost of Sam’s investment is $10,000
Sam calculated his real return to be $10,700
Required:
the interest made from the investment is
10700-10000= $700
Step two:
The ROI is a percentage that tells us the interest made
interest/investment*100
=700/10000*100
=0.07*100
= 7%
The ROI is 7%
