主题:The last Math contest question -- steve
共:💬5 🌺3 新:
Thanks for everybody's help and interest yesterday. We have a last Math contest question here.
Starting with the "1" in the center, the spiral of consecutive integers continues, as shown. What is the sum of the number that appears directly above 2007 and the number that appears directly below 2007?
17 16 15 14 13
5 4 3 12
6 1 2 11
7 8 9 10
(A) 4014 (B) 4016 (C) 4018 (D) 4020 (E) 4022
Alrighty, wish everybody a prosperous Golden Pig Year! Thanks again.
