Explain the term 'homologous series'

A homologous series refers to a group of chemical compounds which share the same functional group, but vary in another sense, such as by the length of the alkyl chain to which the functionality is attached (e.g. the primary alcohols methanol, ethanol and propanol all share a hydroxyl functionality, but vary by increasing CH2 units).
