There are 12 numbers in the first 'circle'
How many in the second?
How many in the third?
What is the pattern for the 4th etc
I have not worked it out, but that is how I would do it.
1 2 3 4 5 6
1 = 5^2 - 5 =20
2 = 7^2 - 6 =43
3 = 9^2 - 7 =74
4 =11^2 - 8 = 113
5 =13^2 - 9 = 160
6 =15^2 - 10 = 215
You can also use this "closed form" formula : a_n = 4 n^2 + 3 n - 2 = a(7) =4*7^2 + 3*7 - 2 = 215
Traviso, you gave someone a point?! Did you break your finger? Maybe you should have an x-ray.
Traviso, you could just try picking your nose. If you can do that without finger pain, then it’s probably not broken.
Thanks for the great solution!!! I would never had know how to do this if it weren't for you!!!
OK I admit I have a mind problem. I’m in good company.
The question here is did you break your finger? Does it hurt when you pick your nose?
You gave a point to this guest, but you never did give a point to Hectictar. Why?
Why do you have such contempt for someone who invests time in your education?
It’s really hard to chill when we have a scatBastard feeding us bulllshit.
I notice there is now 3 points on your thank you post, two points on your question post, and one point on your gripe post.
BUT there is STILL NO POINTS on Hectictar’s answer post.
You’ve pointed up all your posts...many times. This seems like a metaphor for masturrbation?
