dear this answer is wrong because this question is not related to arithmetical progression but this question is related to proportion hence its answer will be 18
oh :(
bro your writing is mast
Its not even 18 as if you consider r=3/2 12×3/2=18 then third term will be 18×3/2 = 27 while its given = 40 so not possible
