Basic objective of this lecture is to present on Mathematical Treasure Hunt: Sequences. It is a tutorial based lecture. Mathematical Treasure Hunts are a fantastic way to engage the students in meaningful revision, or to test and consolidate understanding of a topic. It never ceases to amaze me how much a little competition can bring to life the most lethargic and reluctant of students, and a race against time around the classroom to find all the correct answers can certainly do that.
