2014數(shù)字推理習(xí)題精解(28)

國(guó)家軍隊(duì)文職考試網(wǎng)()解析題目或解析有誤,。1.C。從第三項(xiàng)開(kāi)始,后一項(xiàng)都是前面所有項(xiàng)之和,即1+3=4,1+3+4=8,1+3+4+8=16,故第六項(xiàng)為1+3+4+8+16=32。,24=33-3,60=43-4,120=53-5。則()=63-6=210。3.隔項(xiàng)規(guī)律,奇數(shù)項(xiàng)為:9,7,5,3,1,后一項(xiàng)應(yīng)為-1;偶數(shù)項(xiàng)為:4,-4,4,-4,4,后一項(xiàng)應(yīng)為-4,故選C項(xiàng)。,28-22=6,37-28=9,()-37=12,則括號(hào)中應(yīng)填49。5.C。后一項(xiàng)減去前一項(xiàng)得:3,4,7,11,18。新數(shù)列為二級(jí)等差數(shù)列。故空缺項(xiàng)為47+(11+18)=76。
