can anyone figure this? 9,61,52,63,94,..... what's next? :D

OpenStudy (anonymous):

9 --> 9 = 3² 61-->16 = 4² 52-->25 = 5² 63-->36 = 6² 94-->49 = 7² __ 18-->81 = 9² the number in the blank is 8² with digits reversed, i.e. 8² = 64 --> 46 so the series should read: 9, 61, 52, 63, 94, 46, 18

OpenStudy (diyadiya):

OpenStudy (apoorvk):

NOOOO.. #copy-pastes :/

OpenStudy (anonymous):

You know.. it could actually be 64. If the sequence is squares written backwards, then it is 46. If it is digits of squares written in descending order, it is 64.

OpenStudy (anonymous):

true ^

OpenStudy (apoorvk):

but the others are written backwards, so we write this backwards as well.
