Is Topic 2 (Sequences and Series) in Paper 1 or Paper 2?

Topic 2 is Pure Mathematics and can appear in Paper 1 (100 marks) or Paper 2 Section A (40 marks). Expect financial modelling questions that combine AP/GP with real-world contexts.

Can I use the GC to find terms and partial sums?

Yes. The GC SEQ or RECUR mode is useful for checking your analytic answers. However, you must still show the formula and working - simply quoting a calculator output without method steps will not earn full marks.

Do I need to memorise the standard sum formulas, or are they given?

The AP and GP sum formulas are not provided in the SEAB formula list, so they must be memorised. Standard sigma identities (\$\sum k\$, \$\sum k^2\$) are also not on the reference sheet. ---

Q: What does H2 Maths Notes (JC 1-2): 2) Sequences and Series cover?
A: Arithmetic and geometric progressions, convergence tests, sigma notation, and calculator workflows for modelling recurrence relations.

Before you start
Refresh IP-level arithmetic and geometric sequences. Revisit the MOE definitions so your notation matches the mark scheme and set your graphing calculator (GC) to Exam Mode before drilling.
