IGCSE Booklet 02 – Sequences | Original 15-page PDF

Exact unchanged original IGCSE Booklet 02 – Sequences | Original 15-page PDF.

Keep the original page, question and subpart numbers when following the matching lesson recordings. Each recording may cover selected examples; the complete PDF includes additional practice. This is the original teaching booklet, with its original historical labels and layout.

Spiral learning connection: connect these skills to earlier number, algebra and modelling ideas, then return to them in later problems.

Original-edition clarifications (the PDF itself is unchanged):

• Page 6, Q5(c) uses tₙ = 12tₙ₋₁ with t₁ = 2, so the first terms are 2, 24, 288. The coefficient is twelve, rather than one half.

• Page 15, the intended connection for row U is S − T: n² + 2n − 4ⁿ⁻¹, giving the eighth term −16,304. Finite lists of terms do not determine a unique sequence without an intended pattern.
