Listing in order the first few element of a sequence till the rule for writing down different elements becomes clear .For example, <1,8,27,64,.....>is the sequence whose nth term is n^3. 2. Defining a sequence by the formula for its nth term .For example,the sequence <1,8,27,64,....> can also be written as <  1,8,.....,n^3,.....> or as<n^3:n belongs to N or simply as <n^3>.
