Answer here.

Start from the bottom right and snake up and down having the numbers going from 1 to 25

i think one answer is consecutive numbers starting in the extreme down right of the square to the extreme up left of the square :
From right to left:
(1,2,3,4,5 )->from botton to the top
(6,7,8,9,10)-> from top to botton
(11,12,13,14,15)->from botton to top
(16,17,18,19,20)-> from top to botton
(21,22,23,24,25)->from botton to top

the numbers in the box go from 25-1 counting down by ones vertically, and then up int he next box, then down, then up, then down again. if u dont get it just think 25-1 and ull find an order

the whole table are numbered from 1 to 25. Starting from the bottom right going up is 1 to 5, next column going down is 6 to 10, next column is 11 to 15 going up, next column is 16 to 20 going down, and then the next is 21 to 25 going up. i think. yea.

Note: Numbers on the graph are included in the following sequence set appart in quotes to avoid confusion.

Beginning on the lower right square moving upward:
1, “2″, 3, 4, “5″
square to left of “5″ moving downward:
6, “7″, 8, 9, “10″
square to left of “10″ upward:
11, 12, “13″, 14, “15″
square to left of “15″ downward:
16, “17″, 18, “19″, 20
square to left of “20″ upward:
“21″, 22, 23, “24″, 25

Reading the box left to right, top to bottom
25,16,15,6,5
24,17,14,7,4
23,18,13,8,3,
22,19,12,9,2
21,20,11,10,1

If you start at bottom right corner go up, then down, up, then down, then up, you start at 1 and count to 25, or you can look at it from right to left and see that the rows show that the first and third column add 1, then 3 on 2nd row, 5 on third, 7 on 4th, and 9 on 5th. Assume a figure N which is an odd number between 1 and 10, start at right column, add N for even columns, and 10-N for odd columns

I think I have it, but surely it can’t be THAT easy :S

25 16 15 6 5
24 17 14 7 4
23 18 13 8 3
22 19 12 9 2
21 20 11 10 1
