Question

Which answer describes the type of sequence? 16, 12, 32, 92, ... neither arithmetic nor geometric geometric arithmetic

Answer 1

neither arithmetic nor geometric

Explanation:

16, 12, 32, 92, ...

For arithmetic , there should be a common difference

16, 12, 32, 92, ...

Lets find the difference of two consecutive terms

12-16 = -4

32 - 12 = 20

92 - 32 = 60

Common difference is not same so it is not arithmetic

For Geometric , there should be a common ratio

16, 12, 32, 92, ...

Lets find the ratio of two consecutive terms

`(12)/(16) = (3)/(4)`

`(32)/(16) = 2`

`(92)/(32) = (23)/(8)`

Common ratio is not same , so it is not Geometric

So answer is neither arithmetic nor geometric
