Question

A. Is this an arithmetic sequence? How do you know?

Answer 1

Answer:

a. Yes. The difference is common and equal to $1750

b. $1750

c. $20000 was initial investment

d. This is linear equation with start point of 20000 and slope of 1750:

• y = 1750x + 20000

e. After another 10 years (on the top of 5 given) the investment will be:

• y = 1750*15 + 20000 = $46250

f. After 20 years the value of investment will be:

• y = 1750*20 + 20000 = $55000
