We have that
<span>6,18,54,162,...
we know that
a1=6
a2=18
a3=54
a4=162
a2/a1=18/6--------> 3
a3/a2=54/18-------> 3
a4/a3=162/54------> 3
therefore
a(n+1)=an*3
a1=6
for n=1
a(1+1)=a1*3---------> a2=a1*3--------> a2=6*3------> a2=18
for n=2
</span>a(2+1)=a2*3---------> a3=a2*3--------> a3=18*3------> a3=54
for n=3
a(3+1)=a3*3---------> a4=a3*3--------> a4=54*3------> a4=162
therefore
<span>the equation for the sequence is
</span>a(n+1)=an*3

Answer:
Step-by-step explanation:
Draw a picture. You have an isosceles right triangle. Each leg is 50 ft.
tanθ = 50/50 = 1
θ = arctan(1) = 45°
The answer can either be two to the 7th power or 128
The apples are x and cost $1, and the grapefruits are y and cost $2.
So, 1x and 2y
These together must equal $16
1x + 2y = 16
Hope this helped :)
