The Weil conjectures are famous conjectures formulated by André Weil in 1949.

Hailey used 4 identical sticks to form a square as shown below. She then formed a pattern using more of the sticks.
(a) How many sticks are used to form 13 squares?
(b) How many squares are formed using 100 sticks?
(a) Let n = number of squares
Number of sticks = $(n-1) \times 3 + 4 = 3n + 1$
= $3 \times 13 + 1 = 40$
