The key differences between finite and infinite sequences can be tricky for Year 9 students. Let's break it down:

1. What They Mean:

   • A finite sequence has a specific number of terms.
     • For example: (2, 4, 6).
   • An infinite sequence goes on forever.
     • For instance: (1, 2, 3, ...).

2. Understanding the Idea:

   • The idea of infinity can be confusing.
   • Many students find it tough to spot patterns in these sequences.

3. How to Get Better:

   • Try working through examples and practice problems.
   • Use visual tools like number lines to help explain these ideas.

By addressing these points, learning about sequences can get a lot easier and less scary!
