如果有2003名學(xué)生排成一列,按1,2,3,4,3,2,l,2,3,4,3,2,…的規(guī)律報(bào)數(shù),那么第2003名學(xué)生所報(bào)的數(shù)是

A.1

B.2

C.3

D.4

試題答案

C

試題解析

觀察這組數(shù)的特點(diǎn),每6個(gè)數(shù)為一輪,1、2、3、4、3、2,再用2003除以6,看余數(shù),即可確定答案.

解答:2003÷6=333…5,則第2003名學(xué)生所報(bào)的數(shù)是3,

故選C.

點(diǎn)評(píng):本題是一道找規(guī)律的題目,這類題型在中考中經(jīng)常出現(xiàn).對(duì)于找規(guī)律的題目首先應(yīng)找出哪些部分發(fā)生了變化,是按照什么規(guī)律變化的.
