-
\(T_n\) 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.
\[d = T_n - T_{n-1}\]
-
A quadratic sequence has a common second difference between any two successive terms.
-
The general term for a quadratic sequence is \[T_n = an^2 + bn + c\]
-
A general quadratic sequence:
