解答:
解:當(dāng)x=1時,數(shù)列數(shù)列{a
n}的各項為1,1,0,1,1,0,1,1,0,1,1,0…,
所以在前2014項中恰好含有
=671
項為0,即有671項為0;
當(dāng)x=2時,數(shù)列數(shù)列{a
n}的各項為1,2,1,1,0,1,1,0,1,1,0…,
所以在前2014項中恰好含有
=670
項為0,即有670項為0;
當(dāng)x=3時,數(shù)列數(shù)列{a
n}的各項為1,3,2,1,1,0,1,1,0,1,1,0…,
所以在前2014項中恰好含有
=670
項為0,即有670項為0;
當(dāng)x=4時,數(shù)列數(shù)列{a
n}的各項為1,4,3,1,2,1,1,0,1,1,0,…,
所以在前2014項中恰好含有
=669
項為0,即有669項為0;
當(dāng)x=5時,數(shù)列數(shù)列{a
n}的各項為1,5,4,1,3,2,1,1,0,1,1,0…,
所以在前2014項中恰好含有
=669
項為0,即有669項為0;
…
由上面可以得到當(dāng)x=6或x=7時,在前2014項中恰好含有668項為0;
當(dāng)x=8或x=9時,在前2014項中恰好含有667項為0;
故答案為:8或9.
