B but I'm not as sure though
Plug it in your y= screen of your graphing calculator and hit 2nd and then graph. it will give u a table of values
Let the figure number be x.
Then the equation will be:
3x
There will be 3x circles in the figure number x.
So, number of circles in 50th figure will be
= 3(50)
= 3 × 50
= 150 circles
The answer is 112 on the number line
7.407407407407407... (it repeats the 407)
U just had to divide 400 by 54
