### Quick Reference (1)

Arithmetic and geometric progressions

Arithmetic and geometric progressions are particular types of sequences of numbers which occur frequently in business calculations. This leaflet explains these terms, and shows how the sums of these sequences can be found.

### Teach Yourself (1)

Arithmetic and Geometric Progressions

This unit introduces sequences and series, and gives some simple examples
of each. It also explores particular types of sequence known as arithmetic
progressions (APs) and geometric progressions (GPs), and the corresponding
series.

Sequences and limits - Numbas

3 questions. One question on limits of standard sequences. Other two on finding least $N$ such that $|a_n-L |lt 10^{-r},;;n geq N$ where $L$ is limit of $(a_n)$. Numbas resources have been made available under a Creative Commons licence by Bill Foster and Christian Perfect, School of Mathematics & Statistics at Newcastle University.
