53x53 in exponential form is: 532
1 4 9 16 25 36 49 64 81 100 121 144 169 196 225 you see the squared rooted number i see a pattern you do not recognize. the square rooted numbers count by odd numbers increasing such as 1 3 5 7 9 11 13 15 17 19 21 and so on. It worked for me and i went all the way up to the 50's at one point. no not 51 53 55 57 59 but 51x51 52x52 53x53 and so on.
