Balloon decoration on Children's Day.

Balloon 18 is yellow, and there are 14 red balls in the first 32 colored balls.

And so on, the first 32 balloons, 32/5=6 remainder 2, so a * * * is the complete 6 groups, plus a group of the first two balls, red, yellow and yellow, a group of two red balls, a group of the first two balls are red balls, so 2*6+2,1*14 red. If it is a yellow ball, it is 3*6, a *** 18 yellow ball.

The division and simple arrangement analysis investigated in this topic, the divisor is 5, and the whole group is divisible from the high-order division of the dividend 18 or 32, and the remainder is the first balloon of a group. Pay attention to the balloon order, you can analyze it.
