Answer 1

a) is geometric, because the sequence goes up in a certain ratio, and geometric series move up according to a ratio

b)is arithmetic, because the sequence moves up in a fixed difference and in a arithmetic series the difference doesn't change throughout the sequence

c)is arithmetic because it has a fixed difference and is the difference is unchanging through the sequence

d)Geometric because it goes up in a certain ratio, in this case it is (times 10), and since it doesn't have a fixed difference, it isn't arithmetic
