Characteristics of homologous series:
1. The members of a series have same functional group.
2. Two consecutive members of a homologous series differs each other in their composition by –CH2unit.
Example:
Alcohol (-OH)
CH3-OH , CH3-CH2-OH , CH3-CH2-CH2-OH
3. The members of a homologous series can be represented by same general formula.
Example:
Alcohol è CnH2n+1OH
Aldehyde è CnH2n+1CHO
Carboxylic acid è CnH2n+1COOH
4. The members of a particular homologous series have almost same chemical properties due to presence of same functional group.
5. The physical properties(like solubility, melting point, boiling point, state) of members of a homologous series either gradually increase or decrease with increase in molecular mass.
6. The members of a homologous series can be prepared by same or common general method of preparation.
7. The first member of homologous series generally shows certain different chemical behavior than other members of the series.

Answer:
A homologous series is a sequence of compounds with the same functional group and similar chemical properties in which the members of the series can be branched or unbranched.
For example: Methane, Propane
