Question

In geometric progression, the ratio of each number to the preceding one is the same.

Which is an example of a geometric progression?

1, 2, 3

4, 6, 8

3, 21, 35

4, 12, 36

Answer 1

for each sequence you need to check if term2/term1 = term3/term2

for example, for option 1, term2/term1 = 2/1 and term3/term2 = 3/2 so this series is not geometric

apply this method to every answer choice and select all choices that fulfill this requirement
