Mathematics: Sequences and Series

Mathematics support for students at the University of Suffolk.

Arithmetic Sequences

An Arithmetic Sequence is a sequence of numbers which have a common difference between them. For example 3, 5, 7, 9 or 25, 30, 35, 40. For sequences of this nature it is possible to generalise the terms and calculate the sum of the sequences.

Please follow this link to work through a presentation on Arithmetic Sequences.

 

Geometric Sequences

A Geometric Sequence is a sequence of numbers which have a common ratio between successive terms. For example 1, 2, 4, 8, 16, 32, ... have a common ratio of 2 (each term is 2 times the previous).
