问:In a sequence of integers, A, B, C, D, E…, the value of each integer except the first is equal to two more than the product of the previous integer and 2.
means: n+2+2 or 2n+2 or 2(n+2)
比较白痴也许,two more should be 2+? or 2 multiply

意思是 n+2+2,对吧?我也是这么想的 可参考答案却是 2n+2 ,真是晕了
答案是2n+2啊
他说是2+前面一个数*2
前一个数用n表示
不就是2n+2了么呵呵
the product of previous integer and 2 === previous + 2 吧?
and means "+" ?! or "multiply"?!
