Geometric
Explanation:
You can identify a sequence based off of how the next term appears
if it is subtracting/adding you will get a common difference
if it is dividing/multiplying you will get a common ratio
When you look at the change between 7 and 28 it is multiplied by 4
this can be applied onward:
28 x 4 = 112
112 x 4 = 448 etc;
