What are the formulas for arithmetic and geometric sequences
An arithmetic sequence is a sequence in which each term of the sequence is obtained by adding a pre-determined value, called the common difference, to the preceding term. A geometric sequence is a sequence in which each term of the sequence is obtained by multiplying a pre-determined value, called the common ratio, to the preceding term.
