The rule of a series of numbers 5, 8, 11, 14, 17, 20, ..., 200 is: the first number is 5, and each subsequent number is the previous number plus 3, until 200, multiply the series of numbers , what is the number of zeros at the end of the product
一串数5，8，11，14，17，20，…，200的规律是：第一个数是5，以后各数均是前一个数加3，直到200为止，将这串数相乘，积的尾部的0的个数是多少
