Question

12, 42, 72, 102.... Neither Arithmetic Geometric

Answer 1

1) Let 12,42, 72, 102 be the Sequence. Let's find out if there's a common ratio between those numbers

42 -12 = 30

72 -42 = 30

102-72= 30

2) As we can see, there is a common ratio. Each term increases by adding 30 units.

3) So this is an Arithmetic Sequence
