Question

Determine whether the sequence 12, 40, 68, 96 could be geometric or arithmetic. If possible, find the common ratio or difference.

a
It could be arithmetic with d = 28.
b
It could be arithmetic with d = –28.
c
It could be geometric with r = 28.
d
It is neither.

Answer 1

A

Explanation:

it is Arithmetic because if you subtract 12 from 40 you'll get 28 , same for the others. but if you get the common ratio by dividing 40/12 which is 3.333... it's doent work for the sequence
