25,18,18,16,1,14,21,19,n

What's the value of n? Please let me know if the cryptic clue helped and any suggestions on how to improve it.

• All of these numbers are less than 26. Hmm.. Commented Aug 26, 2016 at 16:03
• Yeah, but YRRPANUS_ doesn't seem very word-like :-). Commented Aug 26, 2016 at 16:07
• I'm wondering if these are issue numbers. Commented Aug 26, 2016 at 17:00
• could you please check your puzzLe again if this is correct or not? Commented Aug 26, 2016 at 17:37
• @Kingrames - I thought something similar... but I don't have the means to check. I also considered the fact that the aunts name is "May" so it could have something to do with months... but had no luck down that front either. Commented Aug 26, 2016 at 18:17

The hint refers to

The months (Aunt May), and traversing letters backwards from the end ("walked back")

So,

For the $n^{th}$ month, take the value of the $n^{th}$ last letter. For $l$ = length of month name, wrap around (or take $n := n-l$) if $n > l$.
January, 1st last letter = Y = 25
February, 2nd last letter = R = 18
March, 3rd last letter = R = 18
April, 4th last letter = P = 16
May, 5th last letter = (5-3) 2nd last letter = A = 1
June, 6th last letter = (6-4) 2nd last letter = N = 14
July, 7th last letter = (7-4) 3rd last letter = U = 21
August, 8th last letter = (8-6) 2nd last letter = S = 19

So the solution is

September, 9th last letter = S = 19

• correct on all counts :) Commented Aug 28, 2016 at 16:57
