An=a1+d(n-1)
an=nth term
a1=first term, when n=1
d=common differnce=amount each term increases by
n=which one
so
when n=1, an=40
so a1=40
it seems to increas by 7 each time
an=40+7(n-1)
explicit formula is expanded
an=40+7n-7
an=33+7n is the formula
the domain is natural numbers because you can't have the -3rd term or the 0th term or the 3.24th term
domain is natural numbers
the formula is

<span>Answer: c
Explanation:-
Given:- Actual height of tower is 1450.
Model height of tower is 24.
To find the ratio of height we divide it (24/1450)
hence the answer is c 12:725</span>
Step-by-step explanation:
P = height of Paul.
S = height of Steve.
t = height of Theresa.
P = 1 1/2 t - 16 = 3t/2 - 16
S = 1 1/3 t - 6 = 4t/3 - 6
because Paul and Steve have the same height, we can say
P = S
3t/2 - 16 = 4t/3 - 6
3t/2 - 10 = 4t/3
9t/2 - 30 = 4t
9t - 60 = 8t
t = 60
so,
Theresa is 60" tall.
Paul and Steve are 4×60/3 - 6 = 240/3 - 6 = 80 - 6 = 74" tall
