问题 You are given a series of numbers. Your task is to see how they form a relationship with each other. You have to choose the number that would go next in the series. 2 3 7 17 39

选项 A、58.
B、75.
C、85
D、65

答案 C

解析 2+1=3,3+4=7,7+10=17,17+22=39,继而寻找1,4,10,22之间的规律。1+3=4,4+6=10,10+12=22,3,6,12之间是两倍递增关系,按规律,它们的下一个数值是 12×2=24。22+24=46,39+46=85,故选项C为正确答案。
