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.
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.
