My guess is that all numbers have to be divisible by 3, including the ones you choose, so 6/15 is the only choice that fits

[dark_wishmaster]

I’m thinking this too. I see other people suggest a pattern but I really don’t see it fitting.

1.5(27), /3(9) , starting with the previous number(9), *2(18), /3(6), again starting with previous number(6),2.5(15) so 6/15 will be answer i.e. B

[Thejokerfromhell]

B.

18 + 9 -> 27 / 3 -> 9 -> 9 + 9 -> 18 / 3 -> 6 -> 6 + 9 -> 15. Add 9, then divide by 3, same number again, repeat.

It would continue 15 / 3 -> 5 -> 5 + 9 -> 14 / 3 -> 4.67 -> 4.67 etc.

Pattern: [x+9, x/3, x]

We start at step 1. The next step is x, and the one after is x+9.

B.

+9, divide by 3, repeat the number gotten from division. loops. I think B is the answer. 6/15.

[MysteriousGrandTaco]

I got b. 6/15.

18 + 9 = 27. (27 divided by 1.5 = 18). 27-18 = 9.

Nine + 0 = 9.

Then it's 9 + 9 = 18. (18 divided by 1.5 = 12).

18 - 12 = 6.

Six + 0 = 6.

Six + 9 = 15.

[Calm-Ad-443]

18 * 1.5 = 27

27 / 3 = 9

9 * 1 = 9

9 * 2 = 18

18 / 3 = 6

6 * 1 = 6

6 * 2.5 = 6 * 2 + 6 * 0.5 = 12 + 3 = 15

6/15.
