In a certain deck of cards, each card has a positive integer written on it.
In a multiplication game, a child draws a card and multiplies the integer on
the card by the next larger integer. If each possible product is between 15
and 200, then the least and greatest integers on the cards could be
(A) 3 and 15
(B) 3 and 20
(C) 4 and 13
(D) 4 and 14
(E) 5 and 14
ANS:C
我選D耶...我覺得我是不太了解題目的意思...
請問"a child draws a card and multiplies the integer on
the card by the next larger integer."
這句話是指如果抽到的卡片上面的數字是 n
則 n(n+1) 要在15~200間嗎?
那n+1這個數字,有要是卡片上的數字嗎?
謝謝解惑

1F：推 restingbeast:我想題意就是你所說的抽到n則要乘上(n+1) 下一個整數 02/29 21:30
