If this path is to continue in the same pattern: then which sequence of arrows goes from point 425 to point 427?

(A)

(B)

(C)

(D)

(E)

Answer

Correct choice: (A)

正确答案：（A）

Solution

The path repeats every four numbers. 425 mod 4 =1, 427 mod 4=3, same as from 1 to 3.

路径每四个数字重复一次。425 mod 4 =1，427 mod 4=3，与从1到3相同。
