The pattern that shows the quadratic relationship between the step numbers and the dot is pattern B
How to get the pattern
The pattern sequence is in the form 1, 2, 5, 10
to get the if it is quadratic, we have to check for the forst and the second differences
First difference: 1, 3, 5
second difference : 2, 2
This is constant, therefore it shows that it is a constant indicating a 2nd-degree
