the expression formed by adding the terms of an arithmetic sequence.
Arithmetic Sequence
a sequence in which the difference between consecutive terms is constant.
Common Difference
the constant difference between consecutive terms of an arithmetic sequence.
Common Ratio
the constant ratio between consecutive terms of a geometric sequence.
Finite Sequence
a sequence that has a last term.
Geometric Series
the expression formed by adding the terms of a geometric sequence.
Geometric Sequence
a sequence in which the ratio of any term to the previous term is constant.
Infinite Sequence
a sequence that continues without stopping.
Recursive Rule
a rule for a sequence that gives the beginning term or terms of a sequence and then a recursive equation that tells how a(n) is related to one or more preceding terms.
Summation Notation
Notation for a series that uses the uppercase Greek letter sigma.
