Arithmetic Series
Arithmetic Series An arithmetic series is a sequence of numbers in which each term after
the first is found by adding a constant amount to the previous term.
Arithmetic Series An arithmetic series is a sequence of numbers in which each term after
the first is found by adding a constant amount to the previous term.
The constant amount is called the common difference, symbolised, d.
