Geometric Series An geometric series is a sequence of numbers in which each term after the first is found by multiplying a constant amount to the previous term. 3. Geometric Series An geometric series is a sequence of numbers in which each term after the first is found by multiplying a constant amount to the previous term. The constant amount is called the common ratio, symbolised, r. 4.
