## 3.3 Summary (EMBG6)

• $$T_n$$ 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 $T_n = an^2 + bn + c$
