📌What's in the video: In this video, we will solve a complete question from Questionnaire 472 of the Winter 2026 exam, which deals with a combination of an engineering series and an arithmetic series. We will learn how to analyze a word problem about a book fair, find the initial sales volume, and calculate the total revenue. Next, we will consider a donation distribution that is made as an arithmetic series, find the number of payment months using a quadratic equation. Finally, we will see how to locate the middle terms in an even series and calculate their cumulative value. A detailed step-by-step solution adapted to the 4-unit level. 📌 Link to the question in the video: https://kibinimatika.org/wp-content/u... 📌For all the solutions to this matriculation exam on the Kibinimatika website: https://kibinimatika.org/bagrut471h2026 💬 Join our community on Discord - for questions, answers and guidance: 🔗   / discord   🌐 Our website:https://kibinimatika.org 🔗 For all our study groups and community: https://kibinimatika.org/groop 📚Our groups on Telegram:https://t.me/ovadgroups 🔥Oved Lev's update channel Ari: https://whatsapp.com/channel/0029VbAD... 🧮Link to playlist:    • 🎓 בגרות 472 חורף 2026 שאלה 3-גידול ודעיכה.   Like, comment and subscribe to the channel help the content reach more students!
