Question 2 - Page 167 Is it possible to make a matchstick arrangement that appears in this sequence using exactly 200 sticks? We use the same expression, and put its value 200 Thus, we write 2t + 1 = 200 Solving 2t + 1 = 200 2t = 200 – 1 2t = 199 t = 𝟏𝟗𝟗/𝟐 t = 99.5 Our Number of matchsticks are in decimal, which is not possible Thus, 200 sticks is not possible
