Geometric Sequences and Infinite Series
Work with the common ratio, find any term or sum, and know exactly when an infinite series converges and when it does not.
Choose the right financial formula, handle monthly compounding correctly, and work out loan repayments and outstanding balances without guessing.
By the end, you can
select and apply the correct financial formula for growth, decay, an annuity or a loan.

Financial Maths — Growth, Decay, Annuities and Loans
The formula is the decision
Financial maths has five formulas and almost no difficulty once you have chosen the right one. Nearly every lost mark comes from choosing wrongly, or from getting n and i wrong. 💰
It is also the topic most directly useful after school. A car loan, a home loan and a retirement annuity are all here.
Pass the challenge and it arrives straight away as a PDF. Add it to your CV or LinkedIn, and anyone can check it's real.

Work with the common ratio, find any term or sum, and know exactly when an infinite series converges and when it does not.
Turn a word problem into one equation, differentiate it to find the maximum or minimum, and interpret rates of change in real units.
Apply the addition rule, tell independent from mutually exclusive, read a Venn or tree diagram, and count arrangements without listing them.
Solve linear and non-linear systems by substitution, keep your ordered pairs matched, and handle the exponent-law questions that look harder than they are.
Read a hyperbola from its equation — both asymptotes, the shape, the axes of symmetry and its domain and range — and sketch it with confidence.
