this is a question from GMAT Prep test. I rechecked and the answer is not 81. Is it possible that there is an error???
Someone pls help to solve this. It seems so obvious and simple, but guess it's not!

Checked it again and I think I have copied it correctly. Does anyone know how to paste a snapshot of it on this website forum.

I also agree with 81 based on the question as stated. It'd be helpful to see the exact screenshot (you can press the Print Screen button, paste it into MS Paint or Word, save as a file, and then upload).
I think the answer would be 27 if it was /3m/=m for when m is odd instead of /m/=3m.

18 27 36 54 81 It seems something is missing. Can you repost it in screenshot format? As it is 81 looks correct but until you post the question directly from GMAT Prep, it remains unclear.

Use the printscreen function; shift printscreen and then paste in MS Paint and save or better yet just paste in a reply.

answer is 27 as per GMAT PREP test..i just did it today..even i had selected the answer as 81.....just wondering how the answer is 27...this may not be a straight substitution problem....lets wait and see if some one could answer this...
