$\sf \frac{225}{23} (488)-236b = 4428 \\ \\ \frac{109800}{23} + - 236b = 4428 \\ \\ -236b + \frac{109800}{23} = 4428 \\ \\ -236+ \frac{109800}{23} - \frac{109800}{23} = 4428 - \frac{109800}{23} \\ \\ -236b = \frac{-7956}{23} \\ \\ \boxed{{{\huge{{\bold{b = \dfrac{1989}{1357} }}}}}}$

Solution

1 Simplify $\frac{225}{23}$ ×488 to $\frac{109800}{23}$ 
 $\frac{109800}{23}$ −236b=4428

Subtract $\frac{109800}{23}$ from both sides
−236b=4428− $\frac{109800}{23}$

Simplify 4428− $\frac{109800}{23}$ to − $\frac{7956}{23}$
−236b=− $\frac{7956}{23}$

Divide both sides by −236
b= - $\frac{7956}{23}$ / 236

Simplify $\frac{7956}{23}$ / 236

Simplify $\frac{7956}{23}$ to b= $\frac{7956}{23}$ ×236

Simplify to $\frac{7956}{5428}$

Simplify $\frac{7956}{5428}$ to $\frac{1989}{1357}$

B = $\frac{1989}{1357}$

Given an arithmetic sequence in the table below, create the explicit formula and list any restrictions to the domain.

djyliett [7]

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 $a_n=33+7n$ or $a_n=7n+33$
