PS: n is the sum of the first six consecutive integers greater than T; p is the sum of the first six consecutive integers greater than T+6.
Which of the following is p?
A、n+6
B、n+12
C、n+24
D、n+36
E、n+48
狗主选的是p - n = [(T+7) +...+(T+12)] - [(T+1) +...+(T+6)] = 36
题中p is the sum of the first six consecutive integers greater than T+6 分析:P里面的第一个元素就比T+6大。。就是说起码是T+7,然后consecutive integers, T+8…… 你的理解是P的第一个元素(T+2)是比T+1要大
