Bayan ta buɗe shafuffuka goma na farko, ta lura cewa adadin zane-zane a kowane shafi ya ƙaru da biyar bayan kowane shafi. Hotuna nawa ne a cikin shafuka biyar na farko? Tsarin hankali: Idan shafi na farko yana da zane-zane 5, kuma adadin zane-zane a kowane shafi ya karu da biyar, shafi na biyu yana da 5 + 5 = 10. Jimlar adadin zane-zane a cikin shafuka 2 na farko shine 5 + 10 = 15. A shafi na uku, adadin zane ya karu zuwa 10 + 5 = 15. Shafuka uku na farko suna da jimlar zane-zane 15 + 15 = 30. Shafi na huɗu yana da zane-zane 15 + 5 = 20. Akwai zane-zane 30 + 20 = 50 a shafuka huɗu na farko. Shafi na biyar kuma yana da ƙarin zane-zane 5 fiye da shafi na huɗu, jimlar 20 + 5 = 25. A shafuffuka biyar na farko, Janice ta ga 25 + 50 = shafuffuka 75.
