Question

Explain? Is the sequence geometric? 48, 46, 44, 42, ...

Answer 1

Take any term but the first term and divide it by the previous term, what do you get?

Answer 2

also tell me which terms you're using

Answer 3

44/42 is 1.0476190476

Answer 4

No its not in geometric. Its in Arithmetic

Answer 5

It's more like 42 divide by 44 (44 is the previous term)

So

42/44 = 0.9545

Answer 6

ohh Okay

Answer 7

Now pick another term, say you pick 46


Divide that by the previous term 48


46/48 = 0.95833

Answer 8

okay

Answer 9

You'll see that the two quotients are NOT equal, so there isn't a common ratio

Therefore, this sequence is NOT geometric.
