Remember, an=a1(r)^(n-1) where a1=first term or where n=1 and r=commmon ratio
<span>
</span>
a2/a1=r
<span>
</span>
so if you have the graph, find the y value coresponding to x=1 and that is a1
<span>
</span>
find the y value coresponding to x=2 and taht is a2, do a2/a1 to get r
so like I was saying
well, each term is 1/2 of the previous
20/40=1/2
so r=1/2
and a1=40
so

is da equation
