Question

Two students each write a function, C(n), that they think can be used to find the number of circles needed to make the nth figure in the pattern shown.

Use the drop-down menus to explain why each function does or does not represent the number of circles needed to make the nth figure in the pattern.

Each figure uses 4 more circle(s) than the previous figure because an additional circle is added to the top, bottom, left, and right sides.

the other half i got incorrect.
