Let Cn be the number of circles in the nth design. Then, given the information in the question, Cn = 0 for all n.
A numerical expression is an expression that uses number. For example, if a teacher told you to write four plus six subract two , you would simply write it in number form. 4+6-2.
You cannot write an algebraic expression for that, you need an equation. The equation is n - 6 = 4
Difference in areas = A1 - A2 where A1 and A2 are the areas of the larger and smaller circles. Other expressions will depend on what information about the circles is available: radius, diameter, circumference.

How do you write an expression
X = " a number " X + 20
