Math 12AP - Quadratics Review

 

1. Find the sequences of differences (D1, D2, D3, etc) for each of the following sequences to determine what type of sequence they are: 

a) {1, 28, 95, 220, 421, 716, …}                    b) {0, 15, 40, 75, 120, 175, …}                     

 

2. Generate the first 6 terms for each sequence:

a) tn = 2n2 – 2n                                     b) tn = n3 +5n2 – 10n – 15                    c) tn = n4 – n2
