Answer:
Pattern B
 Explain: 
A quadratic relationship is characterized by constant second differences. 
 
Pattern A 
 
Sequence: 0, 2, 4, 6 
 
First Differences: 2, 2, 2 . . . . constant indicates a 1st-degree (linear, arithmetic) sequence

Pattern B 
 
Sequence: 1, 2, 5, 10 
 
First Differences: 1, 3, 5 
 
Second Differences: 2, 2 . . . . constant indicates a 2nd-degree (quadratic) sequence

Pattern C 
 
Sequence: 1, 3, 9, 27 
 
First Differences: 2, 6, 18 
 
Second Differences: 4, 12 . . . . each set of differences has a common ratio, indicating an exponential (geometric) sequence
