Subtract each pair of successive terms.  What do you observe?

9 - 7 = ??
11 - 9 = ??
13 - 11 = ??

2

tkhunny · Answer

Every time?

i_love_my_nieces · Answer

Yeah.

tkhunny · Answer

Well, then if we ASSUME that this pattern continues indefinitely, this is the definition of an Arithmetic Sequence.  Are you willing to assume that?

i_love_my_nieces · Answer

I don't know so A?

tkhunny · Answer

You have to be willing to assume the continuation of the pattern.  If so, yes.  It is A

Do you know how to detect a Geometric Sequence?

i_love_my_nieces · Answer

IS it A I think it is?!?!?!?!!?!?!

tkhunny · Answer

Didn't we already say that?

The same SORT of thing will find Geometric Sequences.  Just divide, rather than subtract.

If it fails both tests, it is "Other" or "Neither".
It CANNOT pass both tests.  "Both" is just silly.
