To find the ratio, you Will need to find the ratio of the patio, and the ratio of the scale version of the patio.

16 feet x 20 feet = 320 ft.²

(16/4 = 4 in)/(20/4= 5 in)

4 inches x 5 inches = 20 in.²

320 ft.² / 20 in.² = 16 ft.² / 1 square inch

The fifth term of an arithmetic sequence is 100, and the common difference is 4. Find the first three terms of the sequence.
Ronch [10]
\bf a_n=a_1+(n-1)d\qquad 
\begin{cases}
n=n^{th}\ term\\
a_1=\textit{first term}\\
d=\textit{common difference}\\
--------------\\
a_5=100\\
n=5\\
d=4
\end{cases}
\\\\\\
a_5=a_1+(5-1)4\implies 100=a_1+(5-1)4
\\\\\\
\textit{solve for }a_1\textit{ to find the first term}

then use the common difference "d", to get the 2nd and 3rd terms

-------------------------------------------------------------------------------------------

\bf a_5=a_1+(5-1)4\implies 100=a_1+(5-1)4\implies 100=a_1+(4)4
\\\\\\
100=a_1+16\implies 100-16=a_1\\\\ 84=a_1\quad 
\begin{cases}
a_1=&84\\
a_2=84+4\to &88\\
a_3=88+4\to  &92
\end{cases}
