Question

2, 1, 1/2, 1/4, . . .

Arithmetic
Geometric
Both
Neither

Answer 1

Geometric because it goes down by .5 each time...at least how i see it...

Answer 2

is the difference constant (the same)

Answer 3

@undeadknight26 please read the code of conduct. do not give answers

Answer 4

If dividing one term by the previous term always gives the same result, it is geometric.
If subtracting one term from the previous term always gives the same result, it is arithmetic.

Answer 5

@undeadknight26 The sequence 2, 1.5, 1.0, 0.5, 0 "goes down by .5 each time", also. It isn't geometric, however.

Answer 6

@whpalmer4 please look a little closer at the sequence provided

Answer 7

Wait I'm confused....?

Answer 8

Lest there be any confusion, when I said "It isn't geometric, however" in my previous post, I was referring only to my example sequence, and not saying anything one way or the other about the one in this problem.

Answer 9

I think it is B, or C.

Answer 10

Test for arithmetic sequence:
2-1 =
1-1/2 =
1/2 - 1/4 =
Are they all identical? If so, the sequence is arithmetic

Test for geometric sequence:
2/1 =
1/(1/2) =
(1/2)/(1/4) =
Are they all identical? If so, the sequence is geometric

Answer 11

Yes?

Answer 12

@whpalmer4

Answer 13

yes to which?

Answer 14

I think it is Geometric.

Answer 15

@whpalmer4 and @pgpilot326
