Describe how to sketch the fourth figure in the pattern. Then sketch the fourth figure.

The correct answer is: next will be 24 = 16 sections

We have given the three figures
We will have to analyse all the figures to sketch the fourth figure.
In the first figure there are two sections in which one is shaded
In second figure there are 4 sections in which one is shaded
In third figure there are 8 sections in which one is shaded
From this analysis we can conclude that the proportion of number of sections is
2 : 4 : 8
So it can be seen that it is like 2¹:2²:2³
So the next will be 2⁴  = 16 sections
So the fourth figure will be
