This is the tattoo that many of our graduating seniors will be getting and that me and another mentor already have. For spirit of course!

pretty cool man…i would just get 931 written on there, but im not that creative…

Wow, I wish i could give you more than one reputation point. That is seriously hardcore.

How did you figure it out?

For Inspiration and Recognition of Tattoos?

One of our mentors, Richard, an extremely smart and nerdy guy, figured it out.

Nerdy? I’ll take that as a compliment! Especially from my own team!

Now, what do the following number have in common:

1, 3, 7, 13, 21, 31, 43, 57, 73, 91, 111, 133, 157, 183, 211, 241, 273, 307, 343, 381, 421, 463, 507, 553, 601, 651, 703, 757, 813, 871, 931, 993, 1057, 1123, 1191, 1261, 1333, 1407, 1483, 1561, 1641, 1723, 1807, 1893, 1981

Hmmm?

Each successive number is the previous number plus two times the index in the sequence. ( 1 has index 0, 3 is index one and so on.)

It’s also

n^2 - n + 1
