, A. GRADE REVISION OF QUADRATIC SEQUENCE
• A quadratic sequence is a sequence in which the second difference is constant.
• In a quadratic sequence the general equation for the nth term in the sequence is:
T(n) = an2 + bn + c
• Where: n ⇨ the position of the term in the sequence
a ⇨ constant term that is equal to half of the second different
b; c ⇨ constant terms
