IB Maths AA HL SL 1.2 Arithmetic sequences & series
Practise finding terms, common differences and sums in arithmetic sequences, including savings models and equations involving u_n and S_n.
How this is tested
- form simultaneous equations from given terms, then solve for the first term and common difference
- calculate u_n or S_n from an arithmetic model, including cases where S_n is set to zero
- link repeated deposits or fixed yearly increases to expressions such as 5000 + pn
