Question

What is a term to term rule?

Answer 1

Term to term rule:

A term by term rule is used for a sequence in which the next term is obtained from the previous term.

Example: Arithmetic sequence

In an arithmetic sequence, each term (other than the first term) is obtained by adding or subtracting a constant value from the preceding term. The constant value is called a common difference $\left(d\right)$.

$1,3,5,7,9,\cdots \cdots$ is an arithmetic sequence where common difference is $d=2$.
