问题 What is the sum of the first 2,003 terms of the sequence 0,2,7,1,0,2,7,1,0,2,7, 1, ……if the pattern 0,2,7,1 is repeated throughout the sequence?

选项 A、503
B、2010
C、2013
D、5009
E、20030

答案 D

解析若整个序列O，2，7，1，0，2，7，1，…以0，2，7，1循环，那么该数列前2003项的和是多少?
解：本题的正确答案为(D)。由于数列是以0，2，7，1为周期循环，其周期长度为4，所以前2003项共有2003/4=500个周期，并余3项：O，2，7。因此该数列前2003项的和为：500×(0+2+7+1)+(0+2+7)=5009
