Question

tiles of patterns is shown below. Consider function that represents the number of whithe in each figure.Figure 1Figure 2Figure 3Figure 4Select all statements that are true.

Answer 1

Call n the number of figure and w the number of white figures:

w = (n+2)^2 - n^2

w = n^2 + 4n + 4 - n^2 = 4n + 4

w = 4 (n+1)

All those formulas are equivalent.
