Term - Sequence

Concept

Term - Sequence

Terms are the numbers of a sequence. For example, the numbers 44 and 7.57.5 are terms in the set R\mathbb{R} (the real numbers). In the sequence a1, a2,, ai,,an a_1, \ a_2, \ldots,\ a_i, \ldots, \, a_n the term ana_n can represent an arbitrary term in the sequence, where nn gives its position. Alternatively, if the sequence is finite, ana_n can represent the last term of the sequence, and the index nn gives the number of terms in the sequence.
