\(T_n\) is the general term of a sequence.

Successive or consecutive terms are terms that follow one after another in a sequence.

A linear sequence has a common difference (\(d\)) between any two successive terms.
\[d = T_n  T_{n1}\]

A quadratic sequence has a common second difference between any two successive terms.

The general term for a quadratic sequence is \[T_n = an^2 + bn + c\]
