Answer 1

Answer: 4020

Step-by-step explanation:

t=term. v=value

term 1=60

term 2=100

term 2-term 1=

100-60=40

v=40t+b

100=40(2)+b

100=80+b

b=20

v=40t+20

v=40(100)+20

v=4000+20

v=4020

Answer 2

Answer:

4020

Step-by-step explanation:

This is an arithmetic series with first term 60 and common difference 40.

$60+40(n-1) \\ \\ =60+40n-40 \\ \\ =40n+20$

So, the 100th term is 40(100)+20=4000+20=4020.
