WebWhat should we be able to do with quadratic sequences? You should be able to recognise and continue a quadratic sequence You should also be able to find a formula for the nth term of a quadratic sequence in terms of n This formula will be in the form: nth term = an2 + bn + c (The process for finding a, b, and c is given below) WebAn arithmetic sequence is a sequence where each term increases by adding/subtracting some constant k. This is in contrast to a geometric sequence where each term increases by dividing/multiplying some constant k.
