CHAPTER 5 - Sequences and Series
Exercise 5A - Number Sequences

In this video, you will work through every question in Exercise 5A from Chapter 5 of Haese Mathematics SL, building a solid foundation in recognising, describing, and extending number sequences. You will identify sequences generated by adding, subtracting, multiplying, or dividing, describe sequences in words and find next terms, evaluate general terms using explicit formulas like u_n = 2n + 5, choose the correct formula for a given sequence, and evaluate the first five terms of sequences including polynomial and exponential expressions.

📚 Topics Covered:
Generating sequences by repeated addition, subtraction, multiplication, or division
Describing number sequences in words and identifying next terms
Finding specific terms u_n from explicit formulas
Choosing the correct formula from multiple options for a given sequence
Evaluating five terms from sequences including {2n}, {n^2 + 2n}, {2^n}, and {(-2)^n}
Identifying square numbers, cube numbers, and patterns in non-standard sequences
